4 weeks pregnant signs and sensations. Fourth week of pregnancy: the general condition of the mother and the development of the embryo. Should I do an ultrasound?

4 obstetric week of pregnancy- (approximately 5-6 embryonic) is still too short a time to quite clearly feel all the "charms" of an interesting situation. The abdomen is still flat, the baby is not pushing yet. But the woman's body has already seriously begun to prepare for the bearing of the fetus. What is important in the fourth week is the moment that right now the embryo is attached to the wall of the uterus, where it will spend all the time until birth.

We especially note that the 4th obstetric week of pregnancy differs from the embryonic gestational age. Indeed, in obstetric terms, the period is considered from the day of the last menstruation. And the age of the embryo is counted from the day of its conception. Usually both terms differ by 10-14 days.

What does the expectant mother feel at the 4th week? However, if the pregnancy is not planned, then the woman is still waiting for the arrival of menstruation. However, many characteristic signs are already manifesting themselves: causeless irritability, drowsiness, emotional swings, swelling of the mammary glands and quite noticeable pain, slight swelling in the legs and arms may occur. Breast at 4 weeks pregnant becomes extremely sensitive. Toxicosis in its usual manifestation has not yet occurred.

It feels like a slight tension in the lower abdomen. Some are already waking up intolerance to strong odors. Exacerbations of chronic diseases (if any) may occur.

There are cases when, just on the day of the arrival of menstruation, light discharge with blood begins. This so-called doctors implantation bleeding, many take it for menstruation and for some time do not know about pregnancy.

Fetal development at 4 weeks of gestation

Now, after the embryo enters the uterine cavity, it develops at an accelerated pace. In the meantime, the embryo resembles in shape a flat disk with a diameter of about a millimeter - poppy seed.

The round embryo seems to consist of petals. The outer layers of these petals in the future will become the nerves, skin and hair of the baby, and the inner - all the organs. The middle layer will develop into the genitals, muscles and bones, other organs and tissues of the baby's body.

So far, there is no placenta and amniotic sac as such. They will later form chorion And amnion. The yolk sac will provide the process of hematopoiesis for the fetus until a period of 7-8 weeks.

Now the brain is growing rapidly, and the head is growing. If you look at the pictures Ultrasound at 4 weeks pregnant, then you can see the places of the rudiments of the arms and legs, the face, the oral cavity.

The weight of the embryo is still very small: about 0.5 grams, growth does not exceed 1 mm.

On the photo ultrasound at 4 weeks of obstetric pregnancy, the unborn baby looks like a tiny dot - a poppy seed.

What factors affect the development of the fetus

Already, the connection between the embryo and the woman is growing stronger: the blood vessels connect the unborn baby and the mother. Blood passes through the membranes of these vessels like a filter. However, they cannot protect the unborn baby as well as placenta(which has not yet formed). Therefore, there is a high risk of harmful effects on the fetus from the outside: alcohol, tobacco and chemicals from the environment.

What complications can occur at 4 weeks of pregnancy

What to beware of 4 weeks pregnant, is an incorrect laying and development of the organs of the fetus. Risk factors are all sorts of harmful effects: drugs, the habits of the expectant mother, diseases and infections.

For example, a high temperature can increase the risk of developing heart defects in a child in the future. Smoking causes oxygen starvation. Alcohol inhibits the development of the nervous system and brain.

Very high risk right now. miscarriage. So for any discomfort, pain in the lower abdomen or spotting, run to the antenatal clinic without delay.

Fine vaginal discharge transparent (or slightly whitish) without a specific smell. During this period, bleeding due to implantation can occur - a slightly scanty discharge with blood for one to three days. They pose no danger.

Changes in a woman's body at 4 weeks pregnant

The future baby 4 weeks pregnant- this is no longer a lump of cells, but a living organism that is intensively developing in the uterus. The fetus secretes a certain set of hormones that force the female body to rebuild. After all, now the main goal of a woman’s body is to endure and give birth to a child.

At this time, the corpus luteum (it is formed in place of the egg that has already left the follicle) begins to increase in size and intensively produce the hormone progesterone. Then the placenta will do it.

The embryo, already fixed on the wall of the uterus, reproduces hCG, which makes the processes of restructuring of the body noticeable and clearly signals an "interesting situation".

All the physical processes that are taking place now are aimed at only one thing - carrying a pregnancy and preparing for the birth of a child.

Often, already now, a pregnant woman begins to feel the urge to vomit - this is a spasm of small blood vessels. Fluid from the bloodstream is lost, which is rare but can still seriously dehydrate the body.

At 4 weeks of obstetric pregnancy, the fetus begins to produce unique substances. They suppress immune system mother. But this is a natural process: this is how the unborn child is protected from rejection of the fetus during implantation in the uterus. But for a woman, this fact can turn into an exacerbation of chronic diseases that have been sleeping until that time. The danger may be that a woman, not yet suspecting that she is pregnant, begins to take medications that can cause significant harm to the fetus.

However, if pregnancy is expected, then it is worth abandoning medications. And those places where there is a high probability of catching an infection, it is better to bypass.

A remarkable fact: for those who suffer from diseases associated with the immune system, the release of inhibitory substances by the embryo, on the contrary, has a beneficial effect. So, for example, women with type 1 diabetes may forget about insulin injections until the time the placenta is completed. Skin diseases (psoriasis, for example) go into a state of remission and do not remind of themselves for a very long time, or even completely pass without a trace.

Analyzes and medical examinations

On the 4 weeks pregnant while there are no requirements for conducting surveys or passing a mandatory set of tests. Many women at this time only take the test for the first time and see the long-awaited two stripes. It is unlikely that at this time the test can be false. A negative result will show only a poor-quality or expired test.

If the pregnancy was carefully planned, then there will be nothing bad from taking the tests. So the doctor will simply have an extra opportunity to control the changes that the female body undergoes. Of course, if there is a risk of miscarriage, then it is better to be examined once again and make sure that the process is proceeding within the normal range.

At this time, you can safely donate blood to determine the level hCG
. By the amount of hCG, the doctor can determine not only the fact of pregnancy, but also the likelihood of miscarriage, multiple pregnancy, or other pathologies. The norm for one fetus is 50 - 100 mU / ml. for several fruits, this value increases significantly.

A gynecologist during an examination at week 4 will already say for sure that you are pregnant.

Ultrasound at 4 weeks pregnant

If the ultrasonic examination apparatus has high sensitive characteristics, then 4 weeks pregnant in the pictures you can see not only the enlarged corpus luteum, but also the embryo itself.

Is it worth doing ultrasound at such an early stage, the doctor will decide. Although the harmful effects of ultrasonic waves on the embryo or on the pregnant woman herself have not been proven.

Of course, the most useful advice is a healthy lifestyle for the expectant mother. You will have to radically change your habits, give up a lot. But the sacrifice is quite small compared to the miracle - the expectation of the birth of a healthy child.

The expectant mother must provide the growing embryo with good nutrition, access to all the vitamins, trace elements and nutrients necessary for the baby. Therefore, we switch to a balanced diet, organic products, fruits and vegetables.

Don't forget about outdoor walks. It is clear that in a large metropolis it is difficult to find a quiet and cozy place for relaxing walks. Explore the surroundings of your residential area and you will definitely find a square among the stone jungle where you can relax and enjoy the dreams of an unborn child.

Prohibitions and contraindications during pregnancy

Complete rejection of all bad habits- no alcohol, tobacco, drugs. Their action is so terrible that it is better to deny yourself this than to bite your elbows later, realizing that it was you who had such a negative impact on the health and development of your baby.
Refusal of "harmful" food - fast food, fatty, salty, spicy, smoked. Of course, sometimes pregnant women want something like that, so at least cry. Sometimes treat yourself to something tasty, but in very limited quantities.
If you are a staunch vegetarian, then remember that your unborn child is vital for development protein. Step over your beliefs and allow yourself to eat eggs, fish, chicken, and lean meats.
Avoid stressful situations. Avoid strenuous work that makes you nervous and overtired. Any money you can earn is not worth the health of your unborn baby.
Do not lift weights, do not overdo it with.

Sex at 4 weeks pregnant

There are no restrictions on sexual life at this time. If the pregnancy proceeds without complications, you risk nothing. For insurance, you can consult a doctor on this issue. Sometimes a gynecologist advises abstaining from sex for the period of embryo implantation - contractions of the uterine muscles can prevent the embryo from gaining a foothold on the wall.

However, on 4 weeks pregnant sex is perceived differently by different women. In some pregnant women, sexual desire is exacerbated, in others, on the contrary, sexual desire disappears completely.

Sports and physical education

In this matter, caution is needed if you are engaged in professionally active or extreme sports. It is better to refuse such activities for the entire period of pregnancy.

Physical activity during pregnancy, of course, is necessary. But in a certain amount, but better in accordance with the recommendations of the trainer. Already now you can sign up and start attending special courses in gymnastics and fitness for pregnant women. This is also a good opportunity to chat with friends in an “interesting position”. The main thing is that physical activities are fun and do not bring overwork.

Vitamins and medicines at 4 weeks pregnant

The use of drugs should be abandoned. Almost all medications have contraindications for pregnant women and have serious side effects. Any medicine can be taken only after consulting a doctor.

Do not experiment with folk remedies either, consult with a specialist first.

On the 4 weeks pregnant You can not perform any procedures with the use of anesthesia. Therefore, even dental treatment postpone until the third trimester of pregnancy.

Take vitamins only those that are designed specifically for pregnant women. Lack and even an excess of trace elements or, it would seem, useful substances can significantly affect the fetus and its development.

It is in the third week of pregnancy that a fairly large number of women have signs, which may indicate the onset of pregnancy:

Drowsiness
Fast fatiguability
Frequent urge to urinate
Changes in taste preferences
Increased sensitivity to odors
morning dizziness
Nausea and vomiting.

It is especially dangerous during this period to get sick with infectious or colds. Most effective drugs are contraindicated during pregnancy.

A baby in the 4th week of pregnancy is very tiny - its size is 1 mm. The body is formed from germ layers of three types. The outer one is called the ectoderm, the middle one is the mesoderm and the inner one is the endoderm. Certain systems and organs develop from each germ layer in the body.

The cells of the outer leaf give rise to the skin, teeth, nails and hair. The spinal column will be formed from the middle layer, it also becomes the ancestor:

muscles;
vessels;
gonads;
blood;
internal organs.

The inner layer will form the liver, pancreas, lungs and digestive tract.

In addition to the formation of the fetus itself, the cells of its life support will also be formed from the cells:

at the initial stage, this is a chorion - a special sac that will later form into the placenta and will nourish the fetus's body;
on the 4th week, an amnion is laid, from which the fetal bladder is formed;
a yolk sac with nutrients for the life support of the crumbs at first, until the placenta begins to fully function.

A very important stage in the development of the child in the 4th week is the laying of a primitive circulatory system. Already at this time, the child is provided with oxygen. In the villi that connect the mother's body and the fetus's body, primary blood vessels are formed - they carry out oxygen transfer.

twin development

The development of twins has its own characteristics, but in general, the bearing of babies obeys all the laws of physiology. At the 4th week, the embryos are deeply embedded in the uterine endometrium, where they are protected and successfully continue their development. If the embryos separated before implantation, then each child has its own fetal membrane and placenta. Babies can be twins or twins. They receive their food separately, so they do not compete with each other and develop according to the due date.

When a fertilized egg divides, after immersion in the endometrium and implantation of children, one placenta will form. Children may develop their own fetal membranes, and in some cases, when dividing at the 4th week, children have a common amniotic sac. This makes pregnancy more vulnerable, because the condition of the children depends on each other.

As well as during pregnancy with one child, in twins on the 4th week, the laying of germ layers begins to form the most important systems and organs.

Changes in the body of the expectant mother

The well-being of a pregnant woman in the 4th week does not always signal pregnancy. Rather, there are signs of an “interesting situation” at the conception of twins - already at this time a woman feels typical signs of malaise. If a woman takes a pregnancy test at the 4th week, then the results will be undeniable, because the level of human chorionic gonadotropin is significantly higher, which leaves no doubt about the onset of pregnancy.

Uterine changes

The uterus does not particularly increase in size, but there is a qualitative change in its inner lining layer. The villi become thicker, envelop the embryo at the site of attachment. A mucous plug begins to form in the cervical region, which protects against infection.

Chest pain

Some women already at the 4th week feel coarsening of the mammary glands, soreness when touched, increased sensitivity. This is regulated by hormonal status, which changes at conception. Sensations such as if the breast has increased by a couple of sizes. Nipple halos darken, slight pigmentation may appear, but women do not always notice it.

General state

In the 4th week, women may experience fatigue, drowsiness, dizziness and headaches. There is apathy, a sharp change in mood or irritability - these manifestations are individual. An increase in the level of progesterone primarily affects the woman's digestion - flatulence increases, due to which the tummy looks protruding, constipation, heaviness in the abdomen occur. So far, such changes are only due to the fault of hormones, but after they are provoked by a growing uterus.

Discomfort in the back

Very often, it is twin pregnancy that provokes the appearance of pulling pains in the back. Usually they are moderate, disappear after a change in body position.

sex drive

Nature has laid down a decrease in sexual activity in women in the first weeks of pregnancy. The fetus is too small and defenseless, so the expectant mother's sexual desire is reduced in order to protect the child in this way and provide him with all the conditions for reliable implantation and development.

implantation bleeding

With the introduction of the fetus into the uterine mucosa, the so-called implantation bleeding occurs. On the surface of the underwear, you can see a small bloody spot of bright red color. Attentive women already on this basis suspect a possible pregnancy. There is no danger with such bleeding and you should not worry - it only damages the blood vessels of the uterine mucosa. Already with the appearance of this symptom, you can undergo an ultrasound examination.

Allocations

In the 4th week of pregnancy, women may experience heavy discharge. They are transparent or have a whitish tint, thick in consistency. Allocations are directly provoked by changes in the hormonal background, therefore, in the absence of bleeding and spastic pains in the lower abdomen, you should not be alarmed.

At the 4th week of pregnancy, the expectant mother already clearly feels the signs of her new position. This stage of fetal formation is extremely important, because right now the active development of all organs and systems of the unborn child begins. Now a woman needs to take care of her health. The exclusion of external and internal negative factors during this period is the key to happy motherhood.

Signs of pregnancy in the fourth week

At this stage, the woman already understands that she will soon become a mother, because menstruation is most likely absent. Other early symptoms include:

Emotional swing. Due to fluctuations in the level of progesterone in the blood, a pregnant woman has frequent mood swings. This is manifested in tearfulness, irritability, sleep disturbance.
More trips to the toilet. The uterus at 4 weeks slightly increases in size. As a result, the pressure on the bladder increases. Even with incomplete filling, a woman feels the urge to urinate.
Basal temperature, which should decrease slightly 14 days after ovulation, remains elevated.
Drawing sensations in the lower abdomen and in the lumbar region. Not always this symptom is a harbinger of pregnancy. Pulls the stomach often and at the beginning of menstruation. If conception has occurred, such manifestations may indicate the introduction of the embryo into the wall of the uterus and the growth of the reproductive organ itself.
Chest changes. The mammary glands become dense, sometimes the sensitivity of the nipples increases.
Smearing discharge of scanty character. This sign indicates the attachment of the fetal egg to the uterine wall.

The physiological state of a woman changes markedly. There is drowsiness, fatigue. Fatigue is felt even in the morning in the absence of significant physical exertion.

Often, the expectant mother notices an increase in smell and a change in taste preferences. Dishes that she liked before may be disgusting. At the 4th week of pregnancy, toxicosis and weight loss often occur. Nausea and vomiting appear in the morning hours. Sometimes there is sweating, increased salivation. This does not happen to everyone, many women do not experience this unpleasant condition.

Embryo development at this stage

4 weeks of pregnancy is an important period, characterized by the transformation of a fertilized egg into an embryo. Now the embryo is a tiny body that looks very much like a disk of three layers. What happens during this period? The changes are as follows:

The formation of extra-embryonic organs from the outer leaf. The embryo develops an amniotic membrane or amnion, a yolk sac and a chorion. Thanks to them, the respiratory, protective and nutritional functions are performed.
The outer shell is presented in the form of a chorion. It will later become the placenta. The conversion process will take up to 12 weeks. The placenta is very important for the normal development of the fetus. It provides it with oxygen and other vital nutrients. An important role is also played by the vascular network, which appears in the area of contact between the fetus and the uterine wall.
The amnion or amniotic membrane is the cavity in which the embryo will be located in the future. Later it will be transformed into a fetal bladder. In this space, the child is protected from the negative influence of the external and internal environment.
The yolk sac is responsible for hematopoiesis. He performs his role up to 7-8 weeks.
The ectoderm forms the unequal system of the fetus, the skin, organs of vision and tooth enamel.
The mesoderm is transformed into bone, muscle, connective tissue. Forms the reproductive, excretory, circulatory system.
The endoderm is the rudiment of the organs of the respiratory and digestive systems.

The end of the 4th week of pregnancy is called blastogenesis. The head of the embryo at this stage is already marked and resembles a tiny droplet. The initial stage of embryo formation is completed.

What happens to the baby

At the end of the first month of development, the fetal egg passes into the stage of the embryo. It is now growing rapidly and going through a series of changes. Outwardly, it strongly resembles a discoid body with three layers. At the 4th week of pregnancy, a neural plate is formed in a small organism. This is the rudiment of the spinal cord and brain of the fetus. On a tiny head, you can see the rudiments of the eyes. The diameter of the embryo does not exceed five millimeters.

Starting from the end of the first month from conception and ending with the tenth week, there is an active formation of all organs and systems. Some organs even begin their work. At this stage, there is a rather high risk of miscarriage and deviations in the development of the embryo. In this regard, a woman should take care of her health, eliminate bad habits, emotional upheavals and eat right.

The risk of spontaneous abortion remains high until 12 weeks. A young mother must take all necessary efforts to save the life of the fetus.

Changes in the body at 4 weeks of embryo development

After the fertilization of the egg and its attachment to the wall of the uterus, changes begin in the woman's body, which are still little noticeable. The production of progesterone provokes a slight increase and swelling of the mammary glands, an increase in the sensitivity of the nipples.

The pregnant woman quickly gets tired, drowsiness appears. Girls develop toxicosis, which is expressed in dyspeptic disorders, such as nausea, vomiting, flatulence, and belching. Changes in mood are often noted. Many gain weight, which becomes a reason to suspect their interesting position.

6-7 days after conception, the production of chorionic gonadotropin, known to many as hCG, occurs. Against this background, there is a decrease in immunity. This is necessary for the acceptance of the fetus. Without hCG, the body will perceive the fetus as a foreign body and simply reject it.

Chorionic gonadotropin is sometimes found in girls in the absence of pregnancy. Normally, its numbers do not exceed 5 mU / ml. When conception occurs, the amount of hCG increases rapidly. With twins or triplets, which often develop as a result of IVF, the amount of gonadotropin doubles or triples.

Feelings in a woman

It is impossible to say what exactly a pregnant woman will feel at the 4th week of fetal development. All women are different, so their feelings are different. We will name the symptoms that are most common in expectant mothers at this time.

Breast

At the 4th week of pregnancy, the mammary glands increase slightly in size, their sensitivity increases, many girls notice the appearance of veins. This is a completely normal phenomenon, indicating the preparation of the body for the upcoming motherhood. If the chest at this stage was very sensitive, and then stopped hurting, do not worry. During pregnancy, the female body undergoes many changes.

During this period, you need to think about a comfortable bra. In no case should you wear too tight or synthetic underwear. In the future, this may adversely affect lactation and mammary gland health.

Stomach

At the end of the first month after conception, the woman's belly does not increase in size. Although the uterus is starting to grow, it is still invisible outwardly. Forms can be rounded only in case of an increase in appetite and a rapid weight gain.

Often at the 4th week of pregnancy, a woman feels that her stomach is pulling, discomfort has appeared in the lumbar region. This is explained by hormonal changes and the rapid growth of the uterus. These pains are usually transient and do not require medical treatment.

Uterus

Under the influence of progesterone, the genital organ swells, acquires a soft structure. This is necessary for the development of the embryo and the creation of comfortable conditions for a tiny life. The size of the uterus increases slightly.

In addition, this stage is characterized by the formation of a special mucous plug. This is necessary to protect the embryo from infections throughout the entire period of development.

Allocations

A healthy pregnancy is characterized by the absence of menstrual bleeding. In rare cases, the so-called ablution of the fetus is observed, when in the early stages menstruation passes in the usual way or more poorly.

The only normal condition that is accompanied by spotting is implantation bleeding. During the attachment of the embryo to the uterus, a woman has a small amount of blood, but this sign is not always observed.

Normally, the discharge during the period of bearing a baby should be transparent in color, have a mucous consistency. The mucous base also has a cork that closes the entrance to the uterus. It performs a protective function and prevents infection of the fetus. Such a cork leaves just before the birth.

You should worry if the nature of the allocated secret is as follows:

the presence of an unpleasant odor resembling fish or sour milk;
the presence of itching, burning or other discomfort;
I have a curdled discharge (talks about thrush);
brown, yellow, reddish discharge;
the volume of the secret is large, brings discomfort;
the discharge is accompanied by pain and pain.

If one or more of the above signs are present, a woman is advised to seek medical attention immediately.

HCG and progesterone at 4 weeks

After conception, many changes occur in the female body. First of all, the hormonal background changes. This is expressed in the increased production of certain substances, namely progesterone and human chorionic gonadotropin. Each of these hormones performs its own function.

The role of human chorionic gonadotropin (hCG):

maintains the function of the corpus luteum up to 7 weeks;
takes part in the development of the fetus;
contributes to the suppression of immunity, which is necessary for the acceptance of the embryo by the body.

6-7 days after conception, the amount of hCG in the blood of a pregnant woman increases several times daily. Around week 10, the amount of the hormone begins to gradually decrease.

If we talk about the fourth obstetric week, then the amount of hCG here should be approximately 101 - 4870 mU / ml. At the fourth embryonic week, its amount is approximately 1110 - 31500 mU / ml.

In addition to chorionic gonadotropin, at the onset of conception, there is an increase in the production of the hormone progesterone. Its function is as follows:

participation in the formation of some fetal tissues;
stimulation of the growth of the reproductive organ;
decreased immune system function to prevent embryo rejection;
stimulation of the growth of the mammary glands;
an increase in subcutaneous fat in a woman to provide nutrition to the embryo.

What can be seen on ultrasound during this period? Ultrasound is performed using a transvaginal probe. The method helps to confirm the onset of pregnancy, to identify ectopic attachment of the fetal egg and other possible pathologies. At week 4, an ultrasound scan shows the embryo as a small dot, the diameter of which is no more than two millimeters. The fetus at this time is already visualized quite well.

It is not yet possible to see the tissues of the embryo, but after 7-10 days it will be possible to see a small embryo. During this period, the corpus luteum continues to actively produce progesterone. In the ultrasound photo, the fetus looks like a small dot.

By the way, if you want to see the entire calendar of intrauterine development of the fetus by week, you can do it by.

Diagnosis with a test

On the shelves of pharmacies you can find a lot of pregnancy tests, which easily determine the onset of conception from the first days of delay. All of them are based on the indication of hCG in the female body. 7-10 days after the fertilization of the egg, the amount of chorionic gonadotropin in the body is sufficient for the test to fix it. If the result is negative, this may indicate an incorrect determination of the term or the absence of pregnancy. In such a situation, it is recommended to repeat the test after a while.

Such diagnostics is carried out at home. To do this, carefully read the instructions for use from the manufacturer. The procedure should be done in the morning. During this period, the concentration of hCG is highest.

Why does the stomach sip and hurt in the early stages of bearing a baby? During this period, discomfort is considered the norm, if at the same time the woman feels normal, there are no blood discharges and other negative signs.

Pain in the abdomen and back may indicate such problems:

ectopic pregnancy;
diseases of the urinary system (cystitis, pyelonephritis);
risk of miscarriage;
pathology of the digestive system (ulcer, gastritis, hepatitis, pancreatitis);
inflammation of the ovaries;
frozen pregnancy.

If the pains are frequent and intense, you should not risk your health and the health of a tiny organism.

Pain in the lumbar region

In the lumbar region, pulling and uncomfortable sensations at week 4 can occur under the influence of various reasons. Normally, if these pains are moderate and passing spitting. Usually this indicates an increase in the size of the uterus and the preparation of the osseous-ligamentous apparatus for bearing a baby.

The causes of pathological pain include:

overweight and increased load on the spine;
diseases of the spinal column that arose before pregnancy;
kidney pathology.

If you find such pain in yourself and the increase in their dynamics, you should definitely consult a doctor. Timely diagnosis of certain problems will help to eliminate many complications in the future.

Bloody or brown discharge

As already mentioned, normally spotting in the early stages of pregnancy can be observed only in the case of implantation bleeding and during ablution of the fetus, when menstruation occurs after the onset of conception. In other cases, brown, pink, and bloody discharge may indicate the presence of such problems:

ectopic pregnancy;
freezing of the embryo;
cervical erosion;
incipient miscarriage.

Scanty light brown spotting may appear after a gynecological examination or sexual intimacy. Do not hesitate to inform your gynecologist about the appearance of such a sign. If the problem is detected in a timely manner, this significantly increases the chances of saving the baby.

Causes of elevated body temperature

4 weeks is the first trimester of pregnancy. This period is very exciting for the expectant mother, because she has not yet had time to get used to her new position. As a result, she has many questions. One of them - why can the body temperature rise?

First, let's figure out what the basal temperature should be. This figure varies depending on the woman's cycle. It is known that during the period of ovulation, BBT rises by 1-2 degrees. After 12-14 days, it decreases. When pregnancy occurs due to the production of progesterone, the indicators remain elevated. Therefore, if at week 4 the temperature remains within 37 - 37.3 ° C, then this is an absolutely normal state.

The situation is different if the thermometer readings are quite high and amount to 38-39 ° С. Such marks may indicate serious problems. These include:

inflammatory diseases of internal organs;
ectopic or missed pregnancy;
flu, SARS and acute respiratory infections.

If the temperature was caused by a common cold, a woman is advised to drink plenty of fluids, eat fruits and vegetables with a high content of vitamin C. Drug treatment should be carried out only as directed by a doctor. The specialist will help you choose pills that can not harm the fetus at 4 weeks.

You can not neglect your health while carrying a baby. During this period, the expectant mother is responsible not only for her life.

An ectopic pregnancy is a rather dangerous condition. If it is not diagnosed in a timely manner, the consequences will be extremely negative. In order to suspect a pathology in a timely manner, one should know its symptoms. These include:

lack of menstruation;
toxicosis;
swelling and enlargement of the breast;
pulling sensations in the back and abdomen;
maintaining basal body temperature within 37-37.3°C;
change in emotional state.

With the further development of the pathology, a woman is often diagnosed with severe pain, bleeding. Treatment is either medical or surgical.

The following factors can provoke an ectopic pregnancy:

inflammatory diseases of the reproductive system;
infectious diseases;
congenital diseases of the fallopian tubes;
hormonal disorders in the female body;
bad habits (alcohol, smoking);
transferred abortions;
the presence of an intrauterine device.

The most dangerous is the attachment of the fetal egg in the ovary. The growth of the embryo provokes a rupture of the organ, which is accompanied by acute pain, bleeding, nausea, vomiting and other formidable signs. In the absence of timely assistance, a fatal outcome is possible.

Bearing a child is a complex and lengthy process, during which something often does not go according to plan. Fading pregnancy can occur for the following reasons:

genetic disorders of the fetus;
hormonal failure in the mother's body;
the presence of sexually transmitted infections (syphilis, gonorrhea, chlamydia);
as a result of serious diseases (flu, rubella, meningitis);
with Rhesus conflict;
due to the abuse of cigarettes or alcohol;
in the presence of two or more abortions in the woman's history.

The freezing of the embryo can also occur as a result of strong physical and psychological stress.

Signs of fetal fading include bloody spotting, a sharp cessation of toxicosis, intense pain in the lower abdomen.

If you experience these symptoms, you should immediately make an appointment with your doctor.

Up to 12 weeks, the risk of involuntary abortion remains quite high. At week 4, a woman should be very attentive to her health, adhere to proper nutrition and a healthy lifestyle.

Symptoms of an incipient miscarriage:

bloody or pink discharge, often containing elements of embryonic tissue;
pain in the lower abdomen and in the back;
dizziness and headache;
sometimes there is nausea, irritability.

A miscarriage can last from several hours to several days.

Is it possible to have sex

Sex is not a contraindication at 4 weeks of gestation. If doctors have not diagnosed the threat of abortion and the woman feels great, sexual intimacy with a partner is not prohibited.

Sexual intercourse is contraindicated in the following situations:

the presence of a threat of miscarriage;
miscarriages or fetal fading in a woman's history;
sexual infections in a partner;
leakage of amniotic fluid;
congenital pathologies of the reproductive organs.

In such situations, it is better to abstain from sex in the fourth week.

Features of nutrition for the expectant mother

It cannot be said that a girl in an interesting position in the early stages of bearing a baby should strictly limit herself in some way. The main thing is that the menu is varied and balanced. On the table should be a large number of vegetables, fruits, cereals, dairy products.

Is it possible to fly by plane

Flying at 4 weeks of gestation is often contraindicated. It is associated with the following conditions:

severe toxicosis, accompanied by frequent vomiting;
the threat of termination of pregnancy;
leakage of amniotic fluid;
exacerbation of chronic diseases;
anemia.

During this period, the body already suffers a colossal load and many changes. It is better for a woman to be at home in a familiar environment.
