Pregnancy 4 weeks symptoms sensations. Fourth week of pregnancy: signs and sensations. In addition, all pregnant women would benefit from taking
The 4th week of pregnancy in obstetrics starts from the first day of the last menstruation, and corresponds to two weeks from the moment of fertilization.
Changes at 4 weeks of pregnancy
The female sex hormone progesterone causes changes in the uterus, preparing it for bearing a fetus. Progesterone reduces the contractility of the uterus, promotes the preservation and more reliable attachment of the fertilized egg to the wall of the uterus.
Progesterone causes the formation of a dense mucus plug, which is located at the exit of the uterus and comes off only just before childbirth. It will protect the future fetus from possible infection from the genital tract.
At 4 weeks of pregnancy, the fertilized egg transforms into an embryo. At this stage, the fertilized egg looks like a disk flattened on both sides, consisting of three layers of cells. Each of them will subsequently give rise to three embryonic tissues, from which the organs and tissues of the unborn child are formed. From the outer layer of cells originate nervous tissue, skin and mucous membranes, hair, lens, from the middle layer - bones and muscles, heart, blood vessels and kidneys, from the inner layer - the gastrointestinal tract, lungs and liver. By the end of the 4th week of pregnancy, the curve of the embryo's body is formed.
During this same period, the extraembryonic organs of the embryo begin to intensively develop, which support its existence until the placenta takes care of it. We are talking about the amnion, chorion and yolk sac.
The amnion (water membrane) surrounds the embryo with a protective membrane that protects it from drying out and mechanical damage. In appearance it resembles a bladder and contains amniotic fluid.
The chorion (villous membrane) is the precursor of the future placenta.
The yolk sac contains a supply of nutrients, and during the first 3 months of pregnancy it performs metabolic and excretory functions.
The size of the fetus at the 4th week of pregnancy is no more than 3 - 4 mm, but it is already securely attached to the wall of the uterus. An ultrasound at 4 weeks of pregnancy most often shows that the embryo is attached to the back wall of the uterus, closer to the side of the ovary from which the egg was released.
Feelings of a woman at 4 weeks of pregnancy
If a woman did not plan to become pregnant, then she may not be aware of her condition, since her health is approximately the same as before her next menstruation, and the belly at 4 weeks of pregnancy has not yet changed in circumference.
An emotional outburst in a woman that arises against the background of a hormonal shift is most often replaced by calm and tranquility, which is one of the conditions for bearing a pregnancy. This is the so-called pregnancy aura, when others notice that a woman’s behavior has changed.
At the 4th week of pregnancy, discharge from the genital tract is normally transparent or whitish, not abundant, and odorless. Their appearance can be explained by the influence of hormones and increased blood flow to the pelvis.
As a rule, the next menstruation does not occur. Bloody discharge at the 4th week of pregnancy can be a sign of an incipient miscarriage; in time, their appearance can be confused with the expected menstruation, without knowing about the interrupted pregnancy.
Mild pain in the 4th week of pregnancy, which occurs in the lower abdomen, is also similar to the harbingers of menstruation. They can be either a manifestation of the body’s adaptation to changes in the uterus, or a sign of some disease, for example, urolithiasis.
Examination results at 4 weeks of pregnancy
It is impossible to suspect it by the shape of the abdomen at 4 weeks of pregnancy, since the enlargement of the uterus at this stage is insignificant. A pregnancy test will show a negative or inconclusive result depending on the fertilization period, because the level of human chorionic gonadotropin in the urine is not high enough. But in the blood it will show high values, just like the pregnancy hormone prolactin.
If a woman controlled her basal body temperature before this period, she may notice a change in the graph - the temperature at the 4th week of pregnancy remains high (37 - 37.4 degrees).
An ultrasound at the 4th week of pregnancy allows you to see the corpus luteum in the ovaries, which is increased in size. At this early stage, this examination is usually done in case of problems with conception. Using high-precision ultrasound machines, at 4 weeks of pregnancy an implanted embryo can also be seen on the back wall of the uterus.
If there is a suspicion of pregnancy, the expectant mother should avoid bad habits such as alcohol and smoking - they can lead to miscarriage or fetal deformities.
It is important to adhere to the correct work and rest schedule; night sleep should be complete. Proper and safe nutrition is the key to a healthy pregnancy.
It may be a good idea to start taking folic acid tablets if you haven't already. It prevents neural tube defects in the unborn fetus.
If there is no bleeding from the genital tract or pain during the 4th week of pregnancy, a visit to the gynecologist during this period is not necessary.

Why is week 4 called a very important period? Because the 4th week of pregnancy is the time when all the systems of the embryo’s body are formed, which will only develop later. A woman should find out about her unique condition as early as possible in order to prevent all risks and start taking vitamins as soon as possible. But this can be quite difficult to do.
A pregnancy test does not always show a positive result, even if the embryo has already begun to develop in the uterus. This depends on the characteristics of the expectant mother’s body and, in particular, on the content of human chorionic gonadotropin in the urine.
Symptoms and signs of pregnancy: 4 weeks
Many women are able to accurately determine their condition from the first days of conception, especially if they became mothers. For others, pregnancy may be asymptomatic until the third month. Of course, the absence of menstruation is the most important sign, but it often makes itself felt, even if the embryo is already fully developing in the expectant mother’s belly.
However, it is during the fourth week of pregnancy that most women experience pronounced symptoms.
A pronounced symptom that conception has occurred is the manifestation of sensitivity of the mammary glands. They increase slightly in size, and dark circles form around the nipples.
Many women note the appearance of toxicosis, which is most often expressed in nausea and rejection of certain types of foods. Nausea usually appears in the morning. The lower abdomen begins to feel tight, and the body temperature can rise to 37 degrees. A woman in the fourth week of pregnancy feels tired and sleepy, and her mood jumps all the time. Often expectant mothers become irritable and whiny, something is constantly bothering them. Such symptoms are also harbingers of menstruation, so it is not surprising that in the early stages women cannot yet determine pregnancy.
Despite the fact that the initial signs of pregnancy at 4 weeks are similar to perdmenstrual syndrome, the expectant mother can intuitively guess that a new life is developing in her. And she can confirm her guesses in four ways.
At this stage, the pregnancy test will already show you two stripes, but only if hCG is present in the urine in sufficient quantities. Almost everyone has heard the abbreviation hCG, but not many know what it really is and why this substance begins to be produced in the body of a woman expecting a child.
Human chorionic gonadotropin is a hormone secreted by the embryonic membrane, or chorion. It is necessary so that the female genital organs are tuned to bearing a fetus. HCG is necessary for the development of the corpus luteum in the early stages of pregnancy. It is especially important as an immunosuppressive substance that prevents the female body from rejecting the fetus. The longer the period, the greater the amount of hCG present in the urine and blood. Its level begins to decrease only in the tenth week.
A pregnancy test will only show two lines if the level of hCG in the mother's body is too high. Which test is preferable to purchase? Currently, inkjet and electronic tests are considered the best, but anyone can show pregnancy, since the algorithm of action is the same for everyone.
The most inexpensive and common are test strips. It is better to use them in the morning, when the level of hCG in the urine is highest.
In order for the test to show a reliable result, it must be used correctly. To do this, you need to find a container to collect urine. If the test is kept in liquid, it may show an incorrect result. The sensitivity of test strips is low.
In cassette versions, the strip with the reagent is located in a plastic cassette. To detect pregnancy, you need to place a few drops of urine in one window and wait until the result appears in the second window. It costs more than strips.
Some of the most reliable are inkjet options, which are both highly sensitive and more convenient to use.
The most modern are digital tests, in which “+” or “-” appear instead of stripes, but the operating principle is similar. The most expensive electronic options also show the gestational age.
And yet, if the level of hCG in the urine is low, the woman will not be able to detect the pregnancy status at 4 weeks.
In this case, it is necessary to donate blood for analysis. This is the most reliable way to detect pregnancy, since a woman expecting a child will definitely have hCG in her blood.
Pregnancy at 4 weeks can be confirmed almost accurately by a doctor. At this time, the uterus is already increasing in size and softening. The doctor determines the presence of an embryo by the blue color of the cervix. At this stage, a mucus plug has also already been formed, which will protect the internal organs from infections from the outside.
- Finally, the fourth way to find out about the fourth week of pregnancy is to undergo an ultrasound. But usually the doctor does not prescribe an ultrasound so early. A woman can undergo this analysis only if the doctor has doubts about the harmonious development of the fetus.
What happens during pregnancy at 4 weeks?
When a woman learns that a fetus is gradually beginning to develop in her belly, she is interested in knowing what is happening at a particular moment in time.
Actually, the fetus is formed, transforming from a fertilized egg into an embryo. It does not yet look like a person at all and is a three-layer flat disk.
Extraembryonic organs are actively forming. They consist of the chorion, amnion and yolk sac. In the early stages, they will protect and nourish the embryo in the abdomen.
The chorion is the outer membrane of the embryo, which will subsequently develop into the placenta. The amnion is the cavity in which the embryo is located. Then it will turn into a bladder with fetal fluid, which will protect the fetus from external blows and become its usual habitat. The yolk sac will provide hematopoietic function until the eighth week.
Also worth noting are the cells of the outer, middle and inner layers, or ectoderm and endoderm. Hair, skin, teeth, and the nervous system will be formed from cells of the first type. The second type of cells includes the skeleton, muscle tissue, blood system and genitals. And from the endoderm - the gastrointestinal tract, liver, pancreas, and lungs. It is worth noting that it is the 4th week that is characterized by the end of such a stage as blastogenesis.
At this stage, the embryo is actively developing inside the female body. At this time, the embryonic organs are not yet formed, but the fetus already has a neural plate, which is the rudiment of the brain, both spinal and brain. The size of the embryo at 4 weeks is only four millimeters. From this moment until the tenth week, the fetal organs will develop and then begin to function.
What should an expectant mother do when she is 4 weeks pregnant?
The early period is a very important time for the development of the embryo. Immediately after a woman finds out that she is expecting a baby, she should begin to take care of herself with redoubled force.
First, you need to make an appointment with a gynecologist, who will look at the condition of the genital organs and eliminate initial risks.
Secondly, you need to change your diet. It is important to take additional vitamins prescribed by your doctor. Why should this be done? Because the lack of one or another element in the process of laying internal organs can cause pathology. For example, a lack of folic acid can lead to impaired brain development. Folic acid is recommended to be used even before conception.
It is necessary to completely reconsider your lifestyle as soon as you find out that a fetus is actively developing in your stomach. Nutrition should become healthy. No alcohol or cigarettes - they should be excluded. Some women cannot give up bad habits, not even suspecting that half of the fetal pathologies are associated with smoking or drinking alcoholic beverages.
Risks in the fourth week of pregnancy
Abdominal pain in the early stages is a fairly common symptom. But if it is too strong or is accompanied by bloody discharge, then you should urgently consult a doctor. Such symptoms may indicate a disease of the genital or urinary organs, an ectopic pregnancy, indicate a threat of miscarriage, or be a sign of various inflammations.
Increased discharge in the early stages is quite normal. However, if the discharge has a strong and unpleasant odor and is characterized by the presence of color, consult a doctor. This is a sign that there is an intrauterine infection. If there is light brown discharge at the beginning of the 4th week, there is no need to sound the alarm. They usually disappear quite quickly.
At the beginning of its development, the embryo is exposed to various risks. In the fourth week, the risk of miscarriage or frozen pregnancy is very high.
The reasons for such situations may be different. For example, a miscarriage at 4 weeks indicates that the woman’s body is not yet ready for pregnancy or that she has serious health problems. Also, a miscarriage may indicate a Rh conflict or be the cause of previous abortions. Frozen pregnancy often occurs in women who carry their first pregnancy into adulthood.
Often an ectopic pregnancy occurs in a woman’s body. It is very important that the doctor is able to identify it in the early stages, otherwise it can later lead to death.
Its symptoms are very similar to a normal pregnancy: menstruation is delayed, breast tenderness appears, body temperature rises, and mood changes. The hormone hCG is present in the blood and urine. But the embryo does not develop in the uterus, but in the fallopian tube for the reason that the fertilized egg cannot enter the uterus. Most often this occurs if a woman has obstruction of the fallopian tubes due to numerous adhesions from inflammatory processes, abortions or hormonal diseases.
If the doctor does not detect an ectopic pregnancy in a woman’s body in time, the tube may rupture, causing internal bleeding. And this very often leads to the death of the patient. Typically, during an ectopic pregnancy, the fertilized egg is removed. Often the fallopian tube is also removed along with it.
What awaits the expectant mother?
When pregnancy is already an established fact, the woman is registered. At 10-13 weeks, the expectant mother will have to undergo the first screening, consisting of a blood test and ultrasound. Screening is necessary in order to exclude many genetic pathologies of the fetus, as well as to check the health of the expectant mother.
The longer the period, the more often the woman will have to appear in the doctor’s office. From this moment on, the health of the expectant mother will be carefully monitored, however, the expectant mother must also take care of herself.
At 4 weeks of pregnancy, implantation of the fertilized egg into the uterine wall continues and in parallel, the formation of an embryo begins, which after some time will turn into a fetus, and then into a newborn baby. The expectant mother does not yet know about the new life developing inside her, but very soon a pregnancy test will give positive results.
We recommend reading:What is implantation?
Normally, fertilization of an egg by a sperm occurs in the fallopian tube. It takes an average of 6-7 days for the fertilized egg to travel from the fallopian tube to the uterus. Once in the uterine cavity, the fertilized egg (at this stage it is called a blastocyst) adheres to the inner uterine lining (endometrium) and begins to secrete enzymes necessary for deeper penetration into the uterine wall. This is implantation.
During implantation, the trophoblast (formed from the outer cells of the blastocyst) begins to actively divide and transform into a kind of villi, which gradually penetrate deep into the endometrium. It starts with these fibers formation of chorionic villi– a structure responsible for providing the embryo with all the necessary substances until the placenta appears.
Around the chorionic villi, lacunae filled with maternal blood are formed, from which the developing small organism draws oxygen and resources for active growth.
Implantation of the fertilized egg in some pregnant women is accompanied by a slight discharge of blood from the genital tract - the so-called implantation bleeding. Its appearance is associated with the destruction of the walls of endometrial vessels under the action of enzymes secreted by the trophoblast. Gynecologists consider this phenomenon as a variant of the norm, but only if it is repeated once and is not accompanied by severe painful sensations.
Human chorionic gonadotropin
After implantation of the fertilized egg, the cells of the developing chorion begin to synthesize a special hormone - human chorionic gonadotropin (hCG). This substance is several times more active than sex hormones in relation to the female reproductive organs.
The main function of hCG is to force the female body to adapt to preserving and maintaining nascent life. Under the influence of hCG, the synthesis of progesterone (pregnancy hormone) increases, stress resistance increases, and a number of other important processes occur.
The detection of hCG in the body fluids of women is used to diagnose pregnancy. Normally, within a few days after implantation, in a concentration sufficient to be determined by available methods, hCG appears in the blood, and in the urine only a week later, so even the most sensitive test can give an accurate result about the presence of pregnancy no earlier than 2 weeks after conception .
Each stage of pregnancy has its own concentration of hCG in the blood, which gives doctors the opportunity to assess how well the pregnancy is progressing. For example, a low rate of increase in the level of hCG is characteristic of, and a sharp decrease in the concentration of this hormone is characteristic of a threatening or already occurred one.
Mother's feelings at 4 weeks of pregnancy
At the 4th week of pregnancy, a woman begins to feel swelling of the mammary glands and increased sensitivity of the nipples. In addition, the expectant mother becomes more irritable, emotionally unstable, gets tired quickly and constantly wants to sleep. Body weight may increase slightly (from 0.5 to 1 kg).
The appearance of these signs is associated with the impact on the female body. In principle, the same substance is synthesized by the corpus luteum of the ovary in the second half of the menstrual cycle in the absence of pregnancy. Therefore, for many women, symptoms such as irritability and breast swelling occur before each menstruation and cannot be regarded as the first signs of pregnancy if there is no delay.
Fetus at 4 weeks of gestation
This week, from a cluster of cells called a blastocyst, the formation of an embryo and extra-embryonic structures (chorion, yolk sac, amnion) begins.
Cells of the embryoblast (inner part of the blastocyst) at 4 weeks are divided into two populations:
- The endoblast from which the yolk sac is formed.
- Ectoblast is the precursor of the amniotic cavity and amniotic fluid.
The embryonic rudiment begins to form from the cells located at the junction of the endoblast and ectoblast. At the 4th week of pregnancy, the future embryo consists of only three layers (sheets) of cells that differ in structure:
- Ectoderm. This leaf will give rise to the child’s skin, hair, eyes, nervous system, tooth enamel, and ears.
- Mesoderm– these are the future muscles, skeleton, blood vessels, heart, kidneys of the baby.
- Endoderm- predecessors of the digestive system, lungs.
By the end of the 4th week of pregnancy, the fertilized egg is no longer called a blastocyst, but a gastrula, and the stage of intrauterine development of the baby is called gastrulation. The size of the embryo at this stage is only about 1 mm(this is less than a poppy seed).
Possible problems
The 4th week of pregnancy, like the 3rd, is a critical period in the baby’s intrauterine development. The embryo is extremely sensitive to the negative effects of radiation, chemicals, drugs, and infectious agents, especially since it has already established a connection with the mother, so practically everything good and bad that is in her blood is transmitted to the child.
In addition, week 4 can be called decisive in terms of immediate prospects. If implantation has occurred and embryo development has begun, the pregnancy will continue. If for some reason the fertilized egg was unable to penetrate the endometrium or the formation of the embryo did not begin, the woman will have another menstruation (possibly with a slight delay) and the fertilized egg will come out along with the menstrual flow. Moreover, the woman will never know about it.
There are many reasons for the death of a child at such an early stage. Most often these are gross developmental disorders, which at this stage are called blastopathies. In addition, the unpreparedness of the endometrium or uterine abnormalities can prevent normal implantation of the fertilized egg. Immune disorders can also play a role, as a result of which the mother’s body simply rejects a foreign object in the face of the embryo (normally, the female body immediately after fertilization begins to release an early pregnancy factor, which suppresses the immune response and thereby contributes to the preservation of the child).
A woman’s lifestyle this week largely determines what, if any, development of the tiny creature inside her will be. That's why very important for the expectant mother:
The expectant mother should eat well, drink vitamin supplements (if prescribed by the gynecologist), walk in the fresh air, do something pleasant for the soul, communicate with loved ones and experience more positive emotions.

Each trimester of pregnancy is incredibly important, even one week of gestation can differ significantly from the next. Thus, the 4th week of pregnancy from conception can be considered as a fait accompli, since according to obstetric terms it will already be the 6th week. The embryo has already managed to attach itself to the endometrium, it is developing rapidly, significantly affecting the body, well-being, external and internal sensations of the mother.
In the fourth week, the implanted embryo affects the well-being of the expectant mother
The very first sign of an interesting situation is the characteristic absence of menstruation. In addition, the pregnant woman experiences the following symptoms:
- Weakness and drowsiness;
- Basal temperature rises to 37 degrees;
- A woman often runs to the toilet;
- Sudden mood changes are observed;
- Habitual loads cause fatigue;
- Taste preferences change dramatically;
- The mammary glands become more sensitive and harden;
- Dyspeptic disorders such as excessive salivation and nausea and vomiting reactions;
- Nagging pain in the lumbar area or abdomen.
Pregnancy can be detected by the level of gonadotropic hormone in the blood, and with the use of special pharmacy strip strips, each mother can conduct urine testing on her own. Among hardware methods, the most common way to determine pregnancy is ultrasound diagnostics.
Transformations in the body
In the fourth week, an embryo is formed from the fertilized egg
The fourth week of pregnancy is characterized by the transition of the fertilized egg to the state of an embryo, which has a three-layer structure. Extraembryonic structures are formed from the outer layer. The middle layer forms the structures of muscle tissue, bone skeleton, excretory and circulatory systems, as well as individual elements of the baby’s reproductive system. From the internal layer, intraorganic structures such as the liver and thyroid gland, the digestive system and pancreas, as well as organic structures of the respiratory system are formed. At this time, the embryonic head is formed, and by the end of the 4th week of pregnancy the initial stage of intrauterine development ends.
How does a pregnant woman change?
A woman can verify her impending motherhood during this time period using pregnancy test strips. If the result is positive, you need to go to a gynecologist, who will register you, send you for the necessary examinations and prescribe vitamins. Not all patients have specific sensations, although under the influence of hormonal changes there are sudden mood swings, touchiness and tearfulness, causeless irritability, etc.
Sometimes mothers are bothered by painful sensations in the abdomen, hypersensitivity of the mammary glands or unusual reactions to familiar odors, an abundant mucous odorless secretion appears, hyperedema, etc.
Progesterone levels
By the arrival of the 4th week of pregnancy, there is a gradual increase in progesterone levels; this hormone is initially produced by the yellow-bodied gland, then the placenta will take on a similar function. This hormonal substance is important throughout pregnancy, because it ensures the readiness of the uterine body to grow the fetus by increasing its size. In addition, progesterone maintains pregnancy by preventing the contraction of the muscle tissue of the uterus and thereby preventing the risks of spontaneous miscarriage.
Gonadotropin hormone levels
During pregnancy, gonadotropin levels increase significantly
The human chorionic hormone gonadotropin actively increases; in the first weeks of gestation, its amount doubles every two days. This hormone maintains the corpus luteum until pregnancy reaches 7 weeks. In addition, hCG has an immunosuppressive effect, preventing embryonic rejection, because at first the female immune system mistakes the embryo for a foreign body.
At four weeks, the exact level of hCG can be determined through a laboratory blood test. It is through the detection of hCG that test strips function to detect conception. Gonadotropin increases, so the test reacts to it by the appearance of a second line on the strip strip.
Uterine body and endometrium
Changes also occur with the uterine body - it softens and swells, making it more mobile. The cervical and uterine mucous membranes acquire a bluish tint, since the blood flow to the female genital organs is significantly increased. And in the cervix itself a plug is formed that performs protective functions - it prevents bacteria from entering the uterine cavity. At this stage, the uterus increases only slightly, without going beyond the pelvic area.
The endometrial layer also undergoes transformations. The embryo has already been implanted into it, so the vascular network begins to actively develop, changing the color of the endometrium to bluish. There is also an active growth of glandular structures, from which the placenta will be formed in the future, but while it is not there yet, the glandular cells provide the embryo with nutrition and oxygen. The endometrium gradually thickens, its thickness at 4 weeks is about 20 mm, which can be seen with ultrasound diagnostics.
Abdomen and mammary gland
With the belly, contrary to the expectations of many new mothers, no changes can yet occur, since the embryo is still the size of a poppy seed, and the uterus is small, so the belly is not yet enlarging. Sometimes painful sensations may bother you, but they are minor and pass quickly. But the mammary gland changes noticeably. There is literally a hormonal revolution going on in the body, so the breasts begin to rebuild, preparing for lactation. It grows symmetrically, increases sensitivity and hardens. Some patients may experience painful discomfort, darkening of the areolas and nipples.
How does a pregnant woman feel at 4 weeks
Many women are concerned about what happens to the child at such an early stage? Usually, ultrasound is not done at such a time, but if the need arises, transvaginal examination determines the completed conception and implantation. Embryonic tissue is not yet visible, but by the end of next week, ultrasound will be able to identify a tiny embryo.
Discharge
In the first weeks of pregnancy, if discharge appears, you should consult a doctor.
At 4 weeks, a pregnant woman may begin to discharge:
- Whitish or transparent, odorless, thick - they are caused by a hormonal revolution and increased blood flow to the genitals.
- Brown discharge is sometimes normal if it has light shades. They are often caused by the final processes of implantation of the embryo and its implantation into the endometrial layer. Dark brown discharge is an alarming sign if it is accompanied by painful symptoms, has an unpleasant odor, or is profuse. This phenomenon often indicates an ectopic or frozen pregnancy, cervical erosion or genital infection.
- Bloody discharge is a particularly dangerous phenomenon because it may indicate a miscarriage. Sometimes they occur as a result of rough sexual intercourse, ectopic implantation of the fetus or frozen gestation, as well as after examination by a gynecologist and cervical erosion.
Any discharge requires medical attention to rule out pathology.
Abdominal and lower back pain
Pregnancy at 4 weeks may also be accompanied by uncomfortable pain in the abdomen. This is due to active embryonic development and changes in the new mother’s body. Also, pulling sensations in the abdomen can bother those patients whose menstruation was also painful.
Gynecologists warn that the 4th week is considered a critical period when a pregnant woman usually gets her period, so a pulling stomach can be caused by uterine tone. It happens that such nagging pain ends in miscarriage or fetal death. Lumbar pain is also considered a fairly common occurrence at this stage of pregnancy. Typically, such a symptom is associated with the restructuring of ligamentous and bone structures.
Colds and fever
Colds are undesirable at this stage, because the embryo is very vulnerable, so even minor factors can negatively affect it. If the cold season has begun, then it is better for mom to avoid crowded places. But temperature can have an extremely negative impact on fetal development. If hyperthermia is 38 degrees or higher, then fetal fading is likely, and sometimes there is a risk of miscarriage. Therefore, even at the planning stage, it is necessary to strengthen the immune system in order to protect the fetus from negative influences.
Toxicosis
Many pregnant women begin to suffer from toxicosis at 4 weeks
Not necessarily, but sometimes it happens that in the fourth week a woman begins to suffer from toxicosis. Typically, young mothers carrying their first child are more susceptible to early toxic syndrome. They are concerned about nausea and vomiting reactions, excessive salivation, intolerance to odors and certain foods. In the morning I am bothered by nausea, which subsides by lunchtime.
What is important
With the onset of conception, mommy will have to radically change her life. The sooner she starts following special recommendations, the better for the future baby.
Sex at 4 weeks
Usually, at this stage, spouses do not yet think about the birth of a new family member, so their sexual activity proceeds as usual. If the couple has been preparing for pregnancy for a long time and already from the first day of the delay they learned about the baby, then the doctor will recommend that they avoid experiments, excessive passion and aggressiveness in bed, so as not to accidentally harm the baby. This is especially important for those patients who could not conceive for a long time or whose previous pregnancies ended in miscarriage. After all, uterine contractions during orgasm can disrupt the process of full and final implantation into the endometrium.
Nutritional Features
The main requirement for a pregnant woman's diet is balance and variety. Fast food and semi-finished products are prohibited, and it is also not recommended to rely on canned food. Meat is only lean, but fish, on the contrary, should be chosen fattier, since it contains more organic acids, for example, salmon, trout or salmon. For sweets, you can treat yourself to marshmallows or marshmallows; chocolate and all kinds of cakes are undesirable now. In general, the diet should consist of cereals and vegetables, fruits and berries, dairy and meat products.
Alcohol
Alcoholic beverages for a pregnant woman are an absolute taboo. Active formation of fetal primordia occurs, so alcohol can lead to congenital deformities or pathologies. Ethanol is one of the strongest toxins that causes disturbances in embryonic development and formation, which can cause the baby to be born with abnormalities. Therefore, for the birth of healthy offspring, a complete abstinence from alcohol is necessary.
Antibiotics
Antibiotics are also dangerous for the embryo, especially at 4 weeks. If you take antibiotics without permission, you can provoke the birth of a baby with abnormalities. Therefore, you should take such drugs only if there are special indications and for medical purposes. There is a category of antibiotic drugs that are allowed for use by pregnant women, however, they should not even be taken at this time.
Results
So, in the fourth week it is already possible to confirm the fact of pregnancy using an ultrasound. Also, the gynecologist will be able to roughly establish the approximate timing of conception and the date of expected birth. At this stage, the active distribution of the cellular structures of the embryo occurs. A woman may notice the very first, still unexpressed manifestations of an interesting situation. It is important to change your life at this stage, since the future pregnancy and health of the baby will depend on its image.
SIGNS OF PREGNANCY AT 4 WEEKS (PHOTO OF THE TUMMY)
The 4th week of pregnancy is characterized by the appearance of signs of pregnancy . At this stage, changes in the pregnant woman’s body associated with pregnancy affect all organs and systems. Due to the formation of a pregnancy dominant in the brain, higher nervous activity becomes aimed at creating favorable conditions conducive to bearing a child, therefore irritability and tearfulness later 4 weeks pregnant will give way to peace and tranquility.
Around 4 weeks of pregnancy, signs suggesting pregnancy , become clearly visible (see photo). Pregnant women experience changes in appetite and unusual taste preferences. You may experience intolerance to certain odors. Already at this stage of pregnancy, vomiting often occurs in the morning, and the smell and appearance of some foods causes drooling and nausea . The gag reflex can be triggered even by touching the root of the tongue with a toothbrush.
Often in the early stages of pregnancy, women experience pain in the lower back and abdomen. Since the likelihood of miscarriage is most likely in the first trimester, such symptoms should be taken seriously.
Many pregnant women are concerned about the question: Why does my stomach hurt at 4 weeks of pregnancy?, and the gynecologist did not reveal any pathologies. There is no need to worry - if the woman feels well and all indicators are normal, pain is explained by physiological changes in the body.
Sometimes abdominal pain is felt from the first days of pregnancy . The abdomen is sensitive to touch, pain in the lower abdomen and in the appendage area is both intense and aching. This symptom may indicate an ectopic pregnancy.
The stomach can also hurt when there is a threat of spontaneous abortion. Spontaneous abortion has several stages: threatening, beginning, abortion in progress, incomplete and complete abortion. The threatening stage is characterized by heaviness and nagging pain in the lower abdomen, as well as pain in the sacral area. When the stage begins, the pain becomes intense and frequent, and spotting appears. The presence of pain in the abdominal area requires consultation with a doctor.
The 4th week of pregnancy is also characterized by extremely pronounced emotional reactions to everyday situations, tearfulness and touchiness, photo. Shifts in the activity of the nervous system are so strong that depression may develop. Emotional disturbances manifest themselves to a greater extent in those women who suffered from premenstrual syndrome .
4 weeks pregnant is also characterized production of human chorionic gonadotropin , which allows using laboratory research methods to determine the presence of pregnancy. Since the amount of this hormone is still small, the research results may be incorrect.
4 WEEKS OF PREGNANCY (FETAL SIZE ON ULTRASOUND)
4 weeks of pregnancy is an extremely important stage in the development of the baby. During this period, it turns from a fertilized egg into a real embryo (photo of the fetus - below). At 4 weeks pregnant Ultrasound will show a disk that consists of 3 germ layers (3 layers of cells). Each germ layer serves as the basis for different parts of the child’s body and has its own name. The outer layer, the ectoderm, will develop into the nervous system, hair, skin, tooth enamel, and eye lenses.
The outer embryonic membrane, the chorion, is involved in the formation of the placenta . At the site of attachment of the embryo to the wall of the uterus, a vascular network gradually forms, connecting the baby with the mother. The placenta will finally form only by the 12th week.
The amnion contributes to the formation of the amniotic sac.
At this time, the chorion, amnion and yolk sac are actively forming, providing the baby with nutrition, breathing, comprehensive protection and biochemical support.
At 4 weeks gestation, the size of the fetus is from 0.36 to 1 mm. (see photo) 
The fetal sac can be visualized in the uterine cavity when pregnancy is 4–5 weeks after the first day of the last menstruation and the fetal size is 1–3 mm. If there is a delay in menstruation , and no fetal sac is found in the uterus, a series of repeat ultrasounds and a test for the presence of the pregnancy hormone are required. If the results of a hormonal test are positive and there is no fetal sac in the uterus, there is a high probability of an ectopic pregnancy.
