The article discusses 4 weeks of pregnancy - what happens to the fetus, and what the woman feels, what the baby looks like at 4 weeks of pregnancy, a photo of him on the ultrasound, what are the most dangerous complications at this time. You will find out what the difference is between obstetric and fetal weeks of pregnancy, which means pulling pain in the lower abdomen or scarlet blood at 4 weeks of gestation, can you have sex in the first trimester, use alcohol, tobacco and harmful foods

4 week gestation - signs and symptoms

At 4 weeks of pregnancy still proceeds unnoticed, but toxicosis may appear.

Pregnancy for a period of four weeks proceeds almost imperceptibly. Some signs of pregnancy at week 4 resemble the arrival of menstruation:

  • pulling pain in lower abdomen,
  • irritability,
  • whitish, odorless,
  • swollen breasts.

This reaction is due to the increased tone of the uterus at 4 weeks of pregnancy, increased blood flow and hormonal changes. Because of these symptoms, a woman may not suspect a successful conception.

Even a test at 4 weeks gestation sometimes gives a negative result, since there is an insufficient amount of human chorionic gonadotropin (hCG) in the urine.

The main sign of pregnancy at this time - the delay of menstruation.

If you have not started your period, take a blood count for HCG. The rate of hCG in the 4th week of pregnancy is from 1110 to 31500 mU / ml. Also one of the indicators of pregnancy is the level of progesterone, which is produced in the yellow body of the ovary, and then in the placenta to prepare the female body for the development of the fetus and subsequent delivery. The permissible rate of progesterone in the 4th week of pregnancy is 63-84.9 nmol / l, a more accurate assessment will give the obstetrician.

There is a difference between obstetric and fetal weeks of pregnancy:

  • obstetric week - this is the gestation period from the first day of the last menstruation, that is, the age of the embryo at this time is 2 weeks less,
  • fetal week is the gestation period from the date of conception.

Accordingly, the 4th week of gestational pregnancy is 6th obstetric week.

Feelings in the fourth week of pregnancy

What are the signs and sensations of the 4th week of pregnancy:

  • slight swelling of the breast,
  • sore nipples,
  • feeling tired, tired,
  • slightly increased waist
  • changes in food preferences,
  • intolerance to certain odors,
  • constipation, increased flatulence.

Sometimes during pregnancy for 4 weeks the stomach hurts as before menstruation.

Also, in some women, the body temperature under the influence of progesterone rises to 37-37.4 and lasts from several days to the end of the gestation period. This is a normal phenomenon, and it is worth worrying only with its further increase.

Quite often in the early period there is increased emotionality, nervousness, tearfulness and touchiness without obvious reasons.

What happens to the embryo at 4 weeks gestation

Child development in the 4th week of gestation involves the gradual transformation of the ovum into the embryo. At this stage, the embryo is a kind of three-layer disk, where each layer is responsible for the formation of the main organs:

  • outer layer - the nervous system, skin, hair, eye lenses, tooth enamel,
  • middle layer - kidneys, skeleton, muscular system, heart, blood vessels,
  • inner layer - liver, pancreas, lungs, digestive system.

What the fetus looks like at 4 weeks gestation - the photo of the embryo resembles an oval poppy seed. The size of the ovum at 4 weeks gestation is 2 mm with a length of 5 mm, and weight - 0.4-0.5 grams.

Ultrasound of the fetus at 4 weeks of pregnancy

It is believed that ultrasound has a negative effect on the development of the embryo in the early stages, and some women have concerns about whether it is possible to do an ultrasound at 4 weeks of pregnancy. Officially, the harm of ultrasound at the 4th week of pregnancy is not confirmed, although there is no evidence of its safety. Gynecologists usually do not recommend doing a study without indications, for example, to determine the fact of pregnancy or the location of the ovum with the symptoms of ectopic pregnancy.

It looks like a fetus on ultrasound at 4 weeks of pregnancy

What shows in the 4th week of pregnancy photos of the fetus and reproductive organs:

  • the uterus - the size should be slightly increased, and the tone is normal,
  • uterine cervix - if the cervical canal is shorter than 30 mm, a diagnosis of cervical insufficiency is possible and treatment will be required,
  • fetal sac with a fetus size at 4 weeks gestation of 2 mm,
  • corpus luteum in the ovary up to 30 mm,
  • dilated uterine vessels that feed a growing egg cell.

What you need to know about the fourth week of pregnancy

In the first 4 weeks of pregnancy, a large restructuring occurs in the woman’s body, so the desire to sleep longer is a normal desire.. During this period, most of the internal forces of the future mother leaves for the child, and she does not have enough energy to carry out the usual amount of household chores. Therefore, try to shift part of the household duties to other family members.

Lifestyle in the fourth week of pregnancy

Tips for rebuilding your lifestyle in the fourth week of pregnancy:

  1. Spend more time outdoors, relax more often.
  2. Wear comfortable clothing and shoes.
  3. Avoid stressful situations.
  4. Give up smoking and alcohol.
  5. Do not stay in crowded places during the cold season.

Nutrition at 4 weeks gestation

Lack of vitamins and minerals can adversely affect the development of the embryo, so be careful with your daily diet.

Eat more fruits and vegetables.

Features nutrition at 4 weeks of pregnancy:

  • Eat fresh organic foods.
  • Exclude from the menu, canned foods, smoked meats, salty and fatty foods, convenience foods, sweets and foods with flavors and dyes.
  • Add dairy products, cereals, lean meats, vegetables and fruits to your diet.
  • Forget about fasting days and diets.
  • Take a multivitamin complex and folic acid.

What kind of vitamins will suit you and your baby, ask your gynecologist.

Ectopic pregnancy - 4 weeks

One of the dangerous complications of pregnancy is ectopic pregnancy. This is a pathology when the embryo does not attach to the uterus, but to the fallopian tubes, cervix, ovaries, or intestines, and begins to develop there. Most often, such an embryo is not viable and can cause internal bleeding.

It is not easy to diagnose an ectopic pregnancy, since it is usually not visible for a period of 1-2 weeks. At 3-4 weeks, the symptoms resemble a normal pregnancy - delayed menstruation, slightly increased basal temperature, toxicosis, sensitive breasts, and also do not cause concern.

For diagnosis, gynecologists pay attention to the indirect signs of ectopic pregnancy at an early period of 4 weeks:

  • negative or weakly positive pregnancy test result,
  • low concentration of hCG in the 4th week of pregnancy
  • bleeding brown or scarlet,
  • the absence of the ovum in the uterus on ultrasound,
  • dull or sharp pains in the ovaries and uterus,
  • low blood pressure
  • high body temperature,
  • dizziness.

If an ectopic pregnancy is not diagnosed in time, it can cause a rupture of the organ to which the egg has attached and bleeding.

Fading pregnancy in the fourth week

Another dangerous complication of pregnancy 4 weeks - missed abortion. This is the death of the fetus, which occurs due to alcohol abuse, infection with fever, high physical exertion and other reasons.

A freezing pregnancy most often happens in the first 3-4 weeks, 8-11 weeks and 16-18 weeks and goes away without any symptoms, right up to the moment of miscarriage.

However, there are several signs that should alert you:

  • pink, red or brown discharge comes out of the vagina,
  • in the 4th week of pregnancy the chest stopped aching,
  • nausea, dizziness, vomiting and other signs of toxicosis suddenly disappeared,
  • temperature increased to 37.5 ° C and more.

If you notice these symptoms, consult your gynecologist for a more accurate diagnosis.

Embryo development

An embryo at 4 weeks gestation (from conception) is as follows:

  • head, torso and limbs - there is already a clear separation,
  • there are visible on the head - eyes, nostrils, upper and lower jaws,
  • facial features, nose - begin to form,
  • the upper limbs are fully formed, the fingers are noticeable, but the baby cannot squeeze them into a fist,
  • the lower limbs are also already developed along with the feet,
  • the intestine is actively formed, it may slightly protrude to form a physiological omphalocele,
  • the umbilical cord is formed, it connects the crumbs with the placenta and mother,
  • the heart becomes four-chamber, the blood circulation through the vessels goes intensively
  • the genital tubercle is already there, and there is a gradual formation of male or female genitalia.

When performing an ultrasound, the egg of the uterus with the embryo is clearly visible. The stage of placentation continues. The quality of relationships built in the mother-fetus-placenta system determines how well this pregnancy will develop.

External signs

Pallor of the skin associated with low blood pressure, progesterone background and toxicosis is often noted. The mammary glands are enlarged. The chest swells and even hurts so that it is impossible to sleep on the stomach. Nipples and areola area darken, but the white line of the abdomen is not noticeable.

The anterior abdominal wall loses its tone, and relaxed intestinal loops with a tendency to bloat create a “pregnancy picture”. Therefore, girls note that their stomach appeared already in the second month of pregnancy, but this is not due to the growth of the uterus and fetus (the embryo is still the size of beans), but due to a decrease in overall muscle tone.

Already at this point, improvement in hair and nails can be noted, less care is required.

For others noticeable changes associated with the behavior of women.

  • Nausea, vomiting . It appears not only in the morning. It can be provoked by various smells of food, harsh aromas of perfumes, even natural human pheromones, which are now perceived more clearly.
  • Changing taste preferences. Often "thin" start to eat "not in itself", sometimes the appetite falls, a girl can lose weight. Pregnant women at the same time may be inclined to salty and sweet (for example, to herring and "eat" cakes). Drooling may occur.
  • Irritability and tearfulness. In the first trimester, girls become very impressionable, sentimental, easily influenced and do not think about the consequences. Characterized by frequent mood changes. One minute can be crying and laughing, and without a special reason. For some, irritability rises - actions that they previously did not pay attention to make them angry and nervous.
  • Fast fatiguability . It is much more difficult to transfer earlier feasible physical activities. I want to sleep longer, move less and stay in peace. Work on night shifts should be suspended.
  • Loss of attention. It is more difficult for pregnant women to perform work requiring high concentration of attention. The ability to memorize large amounts of information is somewhat reduced.
  • Decreased libido. Often there is a temporary decline in interest in sex. Sometimes the natural odors of a sexual partner can exacerbate nausea, which passes by 12-14 obstetric week.

The work of the internal organs

Significant changes undergo internal organs, which are assigned an additional load. This is especially noticeable in the presence of chronic diseases. In the first month of pregnancy may account for their exacerbation. Possible violations are presented in the table.

Table - Changes in the work of the internal organs in the fourth week of pregnancy

What's going on inside

In the fourth week of pregnancy, the woman's body suffers tremendous change. This happens regardless of whether the woman knows about the conception or not.

Before the onset of this term, the embryo is represented in the form of an oblate body formed by three layers. Week 4 is marked by the transformation of the ovum into the embryo itself.

The outer layer of cells is transformed into non-embryonic systems. The formation of the most important systems begins from the cells. Throughout pregnancy, they will perform essential functions for the future baby: breathe, feed the fetus and protect it from the external environment. Three systems:

  • Chorion A placenta will be created from chorionic cells over the next four months. With the help of such a shell, the embryo will be able to perform its respiratory function. In the place where the embryo touches the uterine mucosa, a vascular grid begins to form to feed the embryo.
  • Amniotic membrane creates a cavity in which the embryo fits. When modified, the amnion creates a fetal bladder that will produce amniotic fluid that carries a protective function.
  • The yolk sac provides blood supply to the fetus for up to 7–8 weeks of gestation.
  • The ectoderm - the outer layer - is transformed into the cells of the embryo itself, forming the skin, hair beginnings, the grid of the nervous system.

The mesoderm is the middle of the embryo. Later from them begin to form the beginnings of organs and systems. The beginning of the formation of the circulatory system, muscle tissue and the future of the skeleton. The excretory system is also formed, and the genitals begin their formation.

The endoderm is a cell of the inner region. The internal organs begin to form from them: the digestive organs originate, the lungs and the thyroid gland form.

4 week of pregnancy - the most important stage in the development of the embryo. Begins to form the head future baby, which at this moment does not exceed in its size dewdrop. By the end of 4 weeks, the first stage of embryo formation, blastogenesis, is completed.

Fetal changes

The fetus at the fourth week of pregnancy changes daily. A three-layer embryo acquires a neural plate. Later, the nervous system is formed from it - the spinal cord and brain are designated.

In the same period, the face of the baby begins to take shape. The rudiments of eyes are drawn, a lens is formed. The embryo at this stage is still tiny. Its size does not exceed 5 millimeters, however, all vital organs have already taken their beginning.

Despite the tiny size, in the period from 4 to 10 weeks, all organs and systems will be actively formed. And some of them will begin their work before the birth of the child.

Originating in the womb organism during this period is in the greatest danger, since the shells protecting it only began to form. That is why informing the mother about the occurrence of pregnancy makes sense in the earliest terms in order to adjust lifestyles and habits in preparation for future motherhood.

Maternal changes

At 4 weeks of pregnancy, the expectant mother can already find out about her position with the help of a simple pregnancy test. If positive, you should contact your gynecologist, who will appoint the time of the first examination. The doctor will also recommend multivitamins that should be taken by the expectant mother.

If a pregnant woman takes medicine, you should consult about their effect on the embryo.

Often in the fourth week, there are no pronounced signs of pregnancy. Changes are noticeable only from the emotional state of a woman. A change in hormonal levels provokes a mood jump. A woman may become hot-tempered, whining or irritable.

Physical condition may also change. Feel swelling and changes in the mammary glands, sometimes there is a pulling sensation in the lower abdomen and lower back. There may be discharge mucous consistency, not having a pronounced smell. Toxicosis can occur both at this stage and later.

If a woman attributes all the symptoms to the approaching menstruation, the appearance of nausea and vomiting often indicates that pregnancy has begun.

HCG during 4 weeks

HCG does not stop being produced even at the onset of 4 weeks of gestation. The fertilized egg has already attached to the uterus, and the chorion produces chorionic gonadotropin. The need for this substance is confirmed by its functions:

  • Under its influence, the corpus luteum is maintained until 7 weeks
  • Plays a crucial role in the formation of the fetus itself, helping the embryo in the production of steroids,
  • Neset immunosuppressive effect, thanks to which the woman's body accepts the "alien" body of the embryo and does not reject it.

Chorionic gonadotropin continues to be produced by the chorion for several weeks. At the onset of 10 weeks, its production gradually decreases.

Progesterone

Progesterone is an integral part of pregnancy. Its development is required. Until the placenta is formed, the corpus luteum is involved in the production of the hormone. После чего продуцировать его будет сама плацента.

Необходимость прогестерона организму беременной женщины обусловлена функциями гормона:

  • Impact on the uterus: its growth is ensured, and its reduction is prevented,
  • As a result of increased progesterone in the blood during pregnancy, the necessary subcutaneous fatty tissue begins to accumulate, which will ensure the nutrition of the fetus,
  • An action to reduce immunity is directed to the mother's body so that the “alien” embryo is not rejected,
  • Mammary glands under the influence of hormone transformed for future feeding, and also increase in volumes,
  • Pelvis bundles are prepared for the upcoming delivery,
  • Some germ systems form under the influence of progesterone.

Uterus 4 obstetric week

Changes in the uterus during the 4th week of pregnancy become noticeable during the examination. There is a slight mobility of the body as a result of its softening and swelling. The cervix and the organ itself acquire a bluish tinge as a result of increased blood flow.

The cervix produces a special mucous fluid that forms a plug. Throughout the subsequent pregnancy, it will protect the body from infections in the uterine cavity.

Endometrium

During the fourth week, the endometrium is still changing. Implantation of the embryo into the uterine cavity leads to an increase in the number of blood vessels, which is why the bluish color of the mucous membrane is observed.

The glandular cells formed on the walls of the uterus begin their transformation into the placenta. With the growth of the embryo, the endometrium thickens and forms the placenta.

During examination endometrial thickness is about 2 centimeters.

In the fourth obstetric week of pregnancy, women often confuse changes in the mammary glands with premenstrual syndrome. There is swelling familiar to girls, some nipple soreness. But in addition to similar symptoms, there is a darkening of the nipples and areola, which will certainly tell about pregnancy.

Sensitivity and pain in the nipples caused by hormonal changes aimed at the upcoming change in the functions of the mammary glands.

At this stage, externally, the belly of a pregnant woman does not change. The uterus is still in the pelvic area and has not increased significantly in size. The embryo is actively forming, however, the active phase of its growth will come much later.

Ultrasound Examination

Transvaginal ultrasound examination at obstetric week of pregnancy shows the presence of an embryo in the form of a tiny circle in the uterine cavity. Doctors call this speck "fetal sac", and its diameter reaches only a few millimeters.

During this period, the examination can not show the tissue of the embryo, but you can already see a tiny yolk sac that feeds the embryo.

Examination also reveals an increased size. yellow body of pregnancythat performs the function of feeding the embryo until the placenta can take up the production of the necessary substances.

Ultrasound during this period is carried out rarely. Examination is carried out in order to exclude pathologies, for example, a vesicular skid or ectopic position of the fetus.

Abdominal pain

Abdominal pain can indicate both the normal course of pregnancy and the presence of pathology.

Ordinary pain in normal gestation is of short duration. Spotting is absent, as well as increased pain.

In some cases, pain may indicate the following problems:

  • Indigestion,
  • Pathology of the genitourinary system (often accompanied by frequent urination),
  • Sharp pains may indicate ectopic pregnancy,
  • Pains in conjunction with bleeding may indicate a possible threat of miscarriage or embryo freezing,

In any case, abdominal pain in the 4th week of pregnancy should be a reason to consult a gynecologist, who establish the reasons their occurrence.

Discharge at week 4 can be both normal and worrying. Depending on the nature of the symptom, there are several types of discharge:

  1. White or transparent discharge without a strong odor does not pose a threat. This situation is considered normal. The density of the discharge may vary.
  2. Brown. Hormonal changes in the body of the expectant mother can cause the appearance of light brown secretions. The consistency of their usual, without a strong smell. This situation can tell about the completion of the accession of the embryo to the uterine mucosa. Highlight dark color, accompanied by pain, should alert the woman, especially if they increase in intensity and smell sharply. In this case, you should immediately consult a doctor.
  3. Bloody This type of discharge is dangerous, so an urgent need to consult a gynecologist. The cause of the discharge can be a disease, an ectopic pregnancy or sexual intercourse.

Miscarriage at 4 weeks gestation can occur as a result of a genetically incorrect set in an embryo. Also, the reason may lie in the maternal illness, as well as the performance of disparate physical exertion.

Miscarriages occur within a short time: usually from several hours to several days. Characterized by the situation bloody or brown secretionswhose intensity is increasing. The structure of the secretions may be observed clots or particles of tissue.

Discharges are most often found in conjunction with pain in the lower abdomen, which is spasmodic in nature. Possible increase in body temperature.

4 obstetric week of pregnancy - the most important stage in carrying a child. At this time, laid the foundations of future organs and systems. The embryo during this period is not fully protected, therefore, correction of the behavior and lifestyle of the expectant mother at week 4 is mandatory.

Toxicosis in the 4th week of pregnancy

Some women start toxemia in the early stages of pregnancy, although it is not necessary. With toxemia at 4 weeks of pregnancy, the perception of food and its taste changes, nausea, drowsiness, fatigue, lethargy and heartburn appear, appetite disappears, or a constant feeling of hunger torments. In most cases, primiparous women are susceptible to early toxicosis. Feeling unwell passes by 12-16 week.

Discharge in the fourth week of pregnancy

Be careful if you have a brown discharge in the 4th week of pregnancy - this is a sign of a threatened miscarriage. Especially dangerous is bleeding in the 4th week of pregnancy, which is accompanied by back pain or back pain. Most likely, at this time there is a spontaneous abortion.

Brown spotting in the 4th week of pregnancy also suggests a possible fetal death or ectopic pregnancy. What awaits you:

  • In the first case, doctors advise to wait until the uterus independently clears itself from the remnants of the ovum.
  • In the second case, you will have an urgent revision of the uterine cavity to avoid ruptures of the fallopian tube or another organ and subsequent bleeding.

Another cause of daub in 4 weeks gestation - pathology of the cervix.

Whatever the cause of discharge, consult a doctor immediately. You must accept, regardless of the queue and the availability of free coupons.

Nausea at 4 weeks gestation

Nausea at 4 weeks gestation is one of the signs of early toxicosis. This is the body's natural reaction to the development of a new life. However, if vomiting torments you more than 3 times a day, you lose weight, do not want to eat and drink, complications may occur. Due to lack of fluid in the body and the loss of nutrients, dehydration and vitamin deficiency will begin, which will have a negative impact on the development of the child.

As soon as the frequency of vomiting increases, call the doctor or go to the hospital. With the help of drip you will restore the balance of the liquid.

Stomach ache on the 4th week of pregnancy

The condition when at the 4th week of pregnancy pulls the lower abdomen and aching lower back is one of the most common in future mothers. Such nagging pain is the norm and often occurs in women who have had painful periods in the past. However, in some cases, the symptom, when the lower abdomen hurts in the 4th week of pregnancy, signals a dangerous pathology:

  • ectopic pregnancy,
  • miscarriage,
  • uterine fibroids,
  • inflammatory diseases,
  • diseases of the gastrointestinal tract,
  • diseases of the urinary system,
  • acute appendicitis.

If you have 4 weeks of pregnancy pulls the lower back, do not engage in self-diagnosis and seek medical help.

Temperature at 4 weeks gestation

Future mothers who have not cared enough for their immunity and are sick with a cold can face a temperature of 37.4 ° C or more at 4 weeks gestation. What to do in this case, so as not to harm the baby:

  • If the temperature does not rise above 37.4 ° C, stay at home, drink plenty of fluids and call a doctor to prescribe a cold.
  • If the temperature exceeds the mark of 37.4 ° C, the threat of miscarriage increases, intoxication of the mother's body and impaired fetal development. Call an ambulance and before her arrival, try to bring down the temperature of tea with lemon, water-vinegar compress on the head or raspberries in the absence of allergies.

Can I have sex on the 4th week of pregnancy

Early sex does not harm a woman or her child, with the exception of women with the threat of miscarriage. Therefore, the answer to the question of whether you can have sex on 4 weeks of pregnancy, depends solely on the health of the expectant mother. During this period, a woman has nervousness, irritability, heaviness in the abdomen, fatigue, which negatively affect female libido.

Extrasular organs

The magic of nature also lies in the fact that only one cell provides the little one with everything it needs and even nutrition. Three extranatal organs are responsible for this:

  • chorionlike a hairy pouch is the future placenta
  • amnionwhich will soon become a fetal bladder. It is the so-called protective packaging of the embryo,
  • yolk bag, providing baby baby nutrients. This organ is the most important, because the problems in his work usually lead to miscarriages. According to the state of this body, the doctor will recognize certain data about the pregnancy and the embryo.

By the way, here is an interesting fact for you: for the most part, the male genes are responsible for the external germinal organs of the child.

Future mom

During the fourth week not every woman knows about her pregnancy, because the development of zygotes does not always affect the condition of the future mother.

Pregnancy planning is often an exciting process.because in my head there is always a question: did everything work out? The fourth obstetric week of pregnancy is usually indicated by emotionality.

Also, a woman may be a little lethargic and tired, there may be discomfort in the lower abdomen, a constant desire to sleep or rest. But these sensations can still be compared with the state before menstruation.

The sensitivity of the nipples and breasts, by the way, usually increases. The mammary glands may swell immediately after conception. Even the first signs of toxicosis are possible. At such moments, the girl asks for something "tasty", special. Well, it can happen at all otherwise: it will be very sick from any food or odors. Maybe the other way around: nausea will come, and they will not want to eat at all.

External changes

The fourth week may add 1-2 cm to the waist. Even in the fourth week, women's waistline may increase by 1-2 cm, and clothes that will sit a little differently will let you know. But if pregnancy is not planned, the girl may not notice such minor changes and then should not, do not run to the gym and dietitians. That is why it is so important to be protected.

If pregnancy is desired, you must be on your guard. Then you will definitely notice and be aware of what is happening with you. Weight gain at this time can be explained by hormonal alterations, which in combination with early toxicosis lead to its small loss. If the expectant mother is doing well, there is no cause for concern.

What is worth paying attention to?

From the beginning of pregnancy, one has to look at life from a completely different angle.
If you have not adhered to the recommendations for future mothers, and only on the fourth week you learned about your new condition, something should be changed in your life.

The main requirements for feeding pregnant women are the fullness and balance of the diet. In no case can not arrange drinking diet and fasting days. Fast food, convenience foods and canned food are also not the best food option for the future mom.

Nutrition pregnant week by week

In meat dishes, fat should be kept to a minimum. But on the contrary fish can even take a fat variety.

There is no contradiction here. Just in fatty fish there are a lot of nutrients, but in the animal fat there are no organic acids. But now it is said at all about frying in oil. Fatty fish live in the depths of cold seas and oceans and, therefore, have a fatty layer. Among these types of fish are trout, salmon, salmon.

Among sweet foods, chocolates or cakes should prefer marshmallow or candy.
And of course, vegetables and fruits! Where without them? For the diet of pregnant women, they are important in any form: fresh, stewed, boiled. Do not forget about dairy products and cereals.

Often there are questions: Now, perhaps, the rest of the products under lock and key? What if I really want chips or a burger? If the girl with this regularly overdo it, then of course it is impossible. But periodic one-time actions are not prohibited. Especially if it cheers up a little or helps get rid of nausea. The main thing is that pregnant women use these products in very small doses. A pack of chips, for example, "stretch" for a few days, and not eat in five minutes.

Absolutely and precisely prohibited only one product -alcohol. It is strictly contraindicated for future mothers! And it does not matter what drink is a fortress. All sorts of homemade liqueurs - also alcoholic beverages, which must be excluded.

Poisoning food for the baby at this time is extremely dangerous, because it is better to protect themselves from it. Do not need exotic dishes and products, also do not trust restaurants. Because it is possible gastrointestinal upset, and this, above all - harm to the embryo, which is now very vulnerable.

Protection from harm

The body of a pregnant woman is very unstable now. Some of the protection factors have not yet been formed, and therefore it is extremely important to protect the expectant mother. Better for her would be if you follow these measures:

  • not to contact people who smoke and not to smoke,
  • avoid infection with viral infections
  • do not allow yourself to be in a bad mood, to be exposed only to positive emotions and to be less nervous,
  • Do not change the climate around you, moving from one country to another.

Additional measures

It does not hurt to start rubbing olive oil into the problem areas of the skin even before the tummy begins to grow bigger, because stretch marks will not lift the spirits and decorate the woman.

If the 4th week of pregnancy has gone, pains of an unpleasant nature have not yet begun, she may not yet be aware of her condition. So in the sexual life of a couple at this stage there is no change. But after intimacy, a woman may feel an inadequate heaviness around the labia. But so - not everyone. When conception and pregnancy were planned, were carried out under the supervision of doctors, most likely the sexual life is worth while to interrupt.

If a pregnant woman has already had miscarriages, it is imperative to stop it, in the name of the life and health of the future baby. In some cases, the contraction of the uterus leads to the fact that the fetus cannot either completely or completely attach to the uterine cavity.

Interrupt

About miscarriages, as such, on the fourth obstetric week is rarely said, since pregnancy is not always confirmed. A bleeding during pregnancy, many are taking for the standard monthly.

There are several symptoms that are caused by interruption.

  1. Drawing pain in abdomen. Specifically, pain, not discomfort.
  2. Heavy bleeding with clots.
  3. Brown discharge.

But these symptoms are not in all cases a miscarriage or spontaneous abortion.
Possible and special interruption - abortion. This is the right of every woman.. But it is important to realize the responsibility of this decision, because if it was made on emotions, then no one ruled out that the woman would regret it. And although doctors today carry out this procedure with extreme care, negative consequences are still possible.

So let's summarize:

  1. In the fourth obstetric week, pregnancy can already be confirmed. But it all depends on the method.
  2. The cells that make up the embryo are not easy to divide. There is a kind of "distribution" of functions for each cell.
  3. Signs of pregnancy at this stage with strong care is easy to notice.

On how and in what conditions the woman lives during the fourth obstetric week and during pregnancy, in general, the future development and life of the little one depends.

Signs and symptoms

In obstetric practice, the fourth week of pregnancy is two weeks of gestation from conception. The actual pregnancy has already come, the embryo is still classified as an embryo, but it has already consolidated in the uterus. Теперь его развитие неизбежно, и с каждой новой неделей, включая и 4 неделю, женщина все больше будет ощущать постепенный рост внутри нее новой жизни. А пока первые 4 недели беременности обычно для женщины практически незаметно.Although in some cases, the pregnancy still indicate not yet strongly and implicitly expressed symptoms and signs.

Some of the signs and symptoms of pregnancy at 4 weeks are similar to the symptoms before menstruation. Thus, a woman may notice the appearance of irritability and nervousness, fatigue. In rare cases, a change in taste preferences and slight nausea can be added to everything else, especially due to the intolerance of certain odors.

Feelings during the 4th week of pregnancy

The emotional background of a woman often changes: if some of the women are unaware of having a pregnancy for already 4 weeks, others may have a much more pronounced feeling during the 4th week of pregnancy. Crying, gratuitous touchiness, heightened emotional reaction to irritating factors - all this may indicate a "settling" in the womb of a woman's embryo, which in the future will turn into a little man.

Undergone individual changes and breast on the 4th week of pregnancy: there is swelling of the mammary glands, there is a sensitivity and sore nipples. Again, these changes can be explained by premenstrual syndrome, if a woman does not yet know about pregnancy. In fact, at the 4th week of pregnancy, the breasts change due to the hormonal restructuring of the body, adaptation to the new conditions for further functioning.

All changes occurring in the body, a woman who does not know about pregnancy, "writes off" for the upcoming periods. And just about 4 weeks of pregnancy, according to the laws of anatomy, menstruation should begin, but. In connection with successful fertilization and subsequent implantation into the uterus of a fertilized egg, the periods at 4 weeks of gestation are absent. There is a delay, which can also be considered as one of the symptoms and signs of pregnancy at week 4. In some cases, a pregnant woman may experience bleeding that does not have anything to do with menstruation. This is the so-called implant bleeding, which occurs in connection with the attachment of a blastocyst (embryo at 5-6 days of development) in the uterine wall.

Discharge at 4 weeks gestation

Not only delayed menstruation and bleeding scanty discharge instead of them can be indicated the fourth week of pregnancy. Also, discharge at 4 weeks gestation may be more abundant, have a whitish or transparent color without the presence of any odor. This situation is also explained by hormonal changes, and also by increased blood flow. However, only the discharge at 4 weeks gestation, which does not have color (although it may be white) and odor, and is distinguished by a thick consistency, is considered normal. Bloody, brown, painful discharge, accompanied by pain in the back or lower back, as a rule, have nothing to do with pregnancy.

Bleeding and miscarriage

As well as bleeding in the 4th week of pregnancy, which is usually taken by a woman in the dark about her new position for menstruation. Bleeding at this minimum is usually a miscarriage at 4 weeks gestation. It occurs painlessly, the woman usually does not even understand that she was pregnant and takes the bleeding at 4 weeks of pregnancy for menstruation. Many adverse factors can lead to a fading pregnancy, embryo death and subsequent miscarriage at 4 weeks of pregnancy, such as an infectious disease with a high temperature, alcohol abuse, excessive exercise.

Pregnancy test

Such bitter consequences can overtake the woman if the pregnancy was not planned and expected, because the pregnancy test at 4 weeks of pregnancy usually gives a negative result. The fact is that, in spite of a slight increase in the blood of human chorionic gonadotropin, it is still quite small in the urine. Therefore, a pregnancy test at the 4th week of pregnancy may still not “recognize” the already occurring pregnancy.

Ultrasonography at 4 weeks of pregnancy, in turn, is able to show the corpus luteum of pregnancy, which gradually increases in size, feeding the embryo to the formation and full functioning of the placenta. In addition, the development of progesterone, a hormone responsible for the preservation of pregnancy, also becomes the task of the corpus luteum. In addition to the corpus luteum, highly sensitive ultrasound machines at the 4th week of gestation are able to determine the embryo fixed in the uterus. However, such surveys are extremely rare: at this stage a woman often only suspects her possible “interesting position”, doubting whether she should do the appropriate test.

If the pregnancy test at 4 weeks of pregnancy is not yet able to "determine" the presence of pregnancy, then blood tests for hCG at 4 weeks of pregnancy will quite clearly give a positive answer. Indeed, at this stage, the embryo's membranes “excrete” a much larger amount of hCG into the blood, and its sharply increased blood level confirms the presence of pregnancy. The same applies to progesterone, which for the normal course of pregnancy actively produces a corpus luteum.

Uterus at 4 weeks gestation

Under the influence of progesterone, the uterus undergoes changes at the 4th week of pregnancy. This hormone “helps” to settle in the uterus in the fetus — the uterus, due to the active production of progesterone, swells up, softens, but does not increase in size yet. In addition, a special dense mucus plug forms in the uterus: it will protect the “house” of the baby and himself from infections throughout its intrauterine development.

The fetus at 4 weeks of gestation is still undergoing transformation from the ovum to the embryo itself. Externally, it is similar to a flat disk, which consists of three layers. In the future, they will serve as the basis for the formation of tissues and organs of the baby. Thus, the inner layer will cause the appearance of the lungs, liver, digestive system, pancreas. The middle layer will be the "base" for the formation of the skeleton, kidneys, blood vessels, muscular system, heart. The outer layer, in turn, is responsible for the formation of the skin, head, nervous system, tooth enamel, hair, eye lenses. The size of the fetus at 4 weeks of pregnancy reaches 2 mm, its length is 5 millimeters. Yes, the embryo is still tiny, but its development proceeds rapidly. So, the so-called extra-embryonic organs - chorion, amnion, yolk sac, which are so important for the embryo, are actively developing at this stage. Their main task is to provide nutrition, respiration, biochemical support and the most diverse protection for the baby. In the future, the chorion will turn into a placenta, the amnion - into the bladder.

Hurts and pulls the stomach

The “activity” of the embryo in terms of development and the body of a woman reorganizing in accordance with the new situation often lead to the fact that during the 4th week of pregnancy the stomach hurts and pulls. This situation is explained by the changes that occur in the woman's body. In addition, during the 4th week of pregnancy, the stomach is sore and pulls up often in women, who in the past had menstruation as sore. However, it should be borne in mind that 4 weeks of pregnancy belong to the critical stages - during this period, the period usually began in a pregnant woman. Thus, the “pulling” abdomen may indicate an increase in the tone of the uterus. Unfortunately, it also happens that the painful and pulling sensations end in a deplorable - transient pregnancy and spontaneous abortion (miscarriage).

Cold and temperature at 4 weeks gestation

An ordinary, not at all dangerous under normal condition, cold at the 4th week of pregnancy can lead to a fading pregnancy. During this period, the embryo is unusually vulnerable, influenced by even the most seemingly insignificant factors. It’s just that you shouldn’t be frightened at once and fall into panic about this: nervous breakdown and psychological stress in many cases are even more destructive for the future baby than a cold in the 4th week of pregnancy. If a strong temperature is not observed, it is enough just to exclude trips to crowded places and take care of yourself for several days at home. Rinse with salt water, drink plenty of warm tea with honey, and cough - licorice root syrup will help you quickly deal with cold symptoms.

But the temperature at 4 weeks of pregnancy - about 38 degrees and above - for the development of the embryo is very, very undesirable. High temperatures can affect the development of the fetus, and even lead to miscarriage. Therefore, it is necessary before the onset of pregnancy to prepare for the subsequent bearing of the baby and do everything to strengthen the immune system.

Alcohol is extremely dangerous in the 4th week of pregnancy, which can cause irreversible development of pathologies in the fetus and another cause of spontaneous abortion. As mentioned above, the laying of all organs and systems of the baby is unusually active, therefore, drinking alcohol at 4 weeks of pregnancy has a significant damaging effect on this process. Alcohol, as a highly toxic substance, causes significant disruption of the normal formation and development of the embryo, sharply increasing the risk of giving birth to a child with developmental defects and all sorts of anomalies. Therefore, for those mothers who are interested in the birth of a healthy and strong child, it is more logical to completely eliminate alcohol from the diet from the first weeks of pregnancy. And even better - a few months before its occurrence, in the process of planning a pregnancy and preparing for it.

But sex at 4 weeks of gestation usually does not constitute any harm. True, this applies to those of women for whom the threat of miscarriage is not relevant. Another thing is that in the first weeks of pregnancy a woman is not always aware of her new position, therefore sex at 4 weeks of pregnancy does not undergo any changes. And, of course, we should not ignore the fact that during this period, the expectant mother may not be having sex: the symptoms and signs of pregnancy in the form of irritability and nervousness, fatigue and heaviness in the stomach can already be felt.
