Pregnancy 4 weeks - one of the most important stages in the development of the child

Term 4 weeks of pregnancy is a fairly crucial stage in the formation of the embryo, as the cells of organs and systems laid down in the third week begin to actively develop. And their development can affect a variety of factors, both external and internal.

Internal factors include emotional state of a woman. To external factors - a way of life of the pregnant woman. At this time, you should lead a healthy lifestyle and stop taking any medications, alcoholic beverages, do not smoke, to prevent a violation in the development of the embryo and give birth to a healthy child.

Signs of pregnancy at week 4

The signs of pregnancy at week 4 are manifested, first of all, by the absence of menstrual flow. In addition, the woman has the following symptoms: 

• emotional lability - sudden changes in mood, 
• noted nagreganie and increased sensitivity of the mammary glands, 
• high fatigue under normal loads, 
• dyspeptic disorders in the form of nausea, vomiting and increased salivation, 
• drowsiness and weakness, 
• change in taste, 
• minor traumatic pains in the lower abdomen and / or lower back, 
• possibly rapid urination, 
• basal temperature above 37 ° С.

Also, when carrying out additional examination methods, pregnancy can be detected based on high chorionic gonadotropin content in the blood, urine (with the help of test strips) and during the ultrasound, where the embryo in the uterine cavity is visible.

What happens at 4 weeks of pregnancy?

What happens at 4 weeks of pregnancy, many pregnant women who are in this period want to know. This period is characterized by the transformation of the fetal egg into the embryo itself. The embryo at this time has the form of a flat disc having three layers. 

1. Out of the outer layer of cellular elements, extra-embryonic organs are formed - the yolk sac, the chorion and the amniotic membrane (amnion). These organs perform a protective, nutritional and respiratory function. 
   • Chorion is the outer shell of the embryo, it will form the placenta. Her education will last up to twelve weeks. Through the placenta, the embryo will receive oxygen and the substances necessary for its life. Also, at the site of the embryo's contact with the endometrium of the uterus, a vascular network begins to form. 
   • The amniotic membrane (amnion) is formed as a cavity, where the embryo will be located. In the following, the amniotic membrane will turn into a fetal bladder. Amnion produces amniotic fluid that protects the embryo from shock, drying and provides optimal conditions for life. 
   • The yolk sac is responsible for the hematopoietic function up to seven to eight weeks of pregnancy.
   • Cells of the outer layer (ectoderm) are transformed into skin, hair, nervous system, lens of the eye and tooth enamel. 
2. The cells of the middle layer (mesoderm) are transformed into bone skeleton, connective and muscle tissue, blood and excretory systems and organs of the reproductive system.

From the cells of the inner layer (endoderm), the digestive tract, liver, pancreas and thyroid gland, respiratory system organs are formed.

At 4 weeks of pregnancy, the head of the embryo is formed, it looks like a droplet in this period. By the end of 4 weeks, the initial stage of the intrauterine development of the embryo ends, which is called blastogenesis.

Fetus at 4 weeks gestation

The fetus on the 4th week of pregnancy continues to grow and develop intensively. At this time, it is called an embryo, which is transformed from a fetal egg. The embryo in this period has the appearance of a flat disk with 3 layers, from which later the organs and systems will be formed. At the end of the fourth week, a nerve plate is formed, from which the spinal cord and brain will develop in the future, there are rudiments of glands available, and a face with eye rudiments is formed. A tiny embryo at this time has a size of four to five millimeters.

If you have a 4 week pregnancy, the embryonic period begins. From now until 10 weeks, all your child's organs will start to develop, and some will even begin to function. As a result, this period is the most vulnerable to development damage. At the moment the child consists of two layers: a primary ectoderm and a hypoblast, from which all organs and parts of the body are formed.

The primitive placenta also consists of two layers during this period. Its cells are connected to the tissues of the uterus, so the developed placenta provides the fetus with nutrients and oxygen.

An amniotic sac with an amniotic fluid is also formed in it, which will protect the fetus and yolk sac, which produces red blood cells for the baby.

Important: the development of each child is strictly individual. Our information is designed to give you an idea of the development of the fetus.

Changes in the future mother at 4 weeks of pregnancy

With the help of a pregnancy test, you can finally make sure that you are expecting a baby.

If the test is positive, register for the first prenatal consultation with a gynecologist. In most cases, the doctor will appoint her not earlier than the eighth week, or earlier, in the case of chronic diseases, the appearance of symptoms that need to be checked, or in the event that you have problems with a previous pregnancy.

If you are taking any medications, now it is worth consulting with the doctor how safe they are for the baby.

Before pregnancy, you should take a multivitamin, with a content of at least 400 micrograms of folic acid, with its onset the dose should be increased to 600 micrograms per day.

The next six weeks are important for the development of the child. For the present, the simplified placenta and umbilical cord, which transmit nutrition and oxygen to the child, are already functioning.

If you have tried unsuccessfully to become pregnant within a year or longer, see a doctor, you need a checkup to identify possible problems.

Pregnancy test, "I had a home pregnancy test and received a negative result, but I knew for sure about my pregnancy, I felt it." I waited a few days, and I did another test this morning. "This time, I was right, it turned out to be positive. " - Anonymously

[7], [8], [9]

Sensations at the 4th week of pregnancy

Sensations at the 4th week of pregnancy may be absent. But in most cases, the emotional state of a woman, due to hormonal changes. There are mood swings, increased tearfulness and touchiness, irrational irritability. In addition to disturbances in the emotional sphere, the woman feels engorgement and increased sensitivity of the mammary glands, pains of a pulling character in the lower abdomen and / or lower back are possible, increased mucous secretions without smell, perception of different types of odors and changes in taste preferences are often noted, swelling. Often at 4 weeks of gestation, there is the occurrence of nausea, increased salivation and vomiting.

HCG at 4 weeks of gestation

HCG at the 4th week of pregnancy continues to be produced after implantation of a fertilized egg. The chorionic gonadotropin is secreted by the embryo envelope - the chorion and exerts an effect on the female genitalia, thus directing them to support the pregnancy that develops. The function of chorionic gonadotropin (hCG) is high: 

• provides support in the development and work of the yellow body of pregnancy up to seven weeks, 
• takes part in the secretion of steroids in the fetus, thus participating in the formation of sex in the fetus, 
• has an immunosuppressive effect, thereby preventing rejection of the embryo, which is foreign to the woman's immune system.

Chorionic gonadotropin increases every two to three days in the first weeks, as pregnancy progresses, its level begins to fall. The highest level of chorionic gonadotropin is observed in the eighth to the tenth week, after which it begins to decrease.

HCG at week 4 of pregnancy can be determined by using a laboratory test method, blood is taken for analysis, and a woman can determine its presence in the urine with a test strip.

Progesterone at week 4 of pregnancy

Progesterone at 4 weeks of gestation continues to increase. It produces the yellow body of pregnancy before the formation of the placenta, which in the future will take the production of progesterone on itself. Progesterone plays a significant role not only at 4 weeks of pregnancy, but throughout its entire period. The function of progesterone is as follows: 

• provides the growth of the uterus and prepares it for an increase in the embryo, 
• prevents the contraction of the muscles of the uterus and, thus, prevents the threat of abortion, 
• increases the accumulation of substances in the form of subcutaneous fat required for feeding the embryo and the body of a woman, 
• reduces the work of the immune system, so that the body of a woman does not reject the alien organism of the embryo, 
• provides growth and development of mammary glands, 
• contributes to the preparation of pelvic ligaments for labor, 
• takes part in the development of certain tissues in the fetus.

The content of progesterone at 4 weeks of pregnancy, depending on the laboratory is different and on average is 18 nmol / l. Before passing the analysis on the content of progesterone, it is necessary to stop taking hormonal medications, not to eat and to exclude the effects of stress and physical exertion.

Uterus at the 4th week of pregnancy

Uterus on the 4th week of pregnancy swells, softens, especially in the isthmus region, in connection with which, its easy mobility is noted. Mucous uterus and cervical cervix, due to increased blood flow. In the region of the cervix, a mucus plug is formed, which will perform a protective function, in particular, to prevent the entry of bacterial infection from outside into the uterine cavity. In size, the uterus does not significantly increase at week 4 and does not exceed the boundaries of the small pelvis.

Endometrium at 4 weeks of gestation

Endometrium at the 4th week of pregnancy continues to undergo some modifications after implantation of a fertilized egg. It increases the number of blood vessels (in connection, than it gets cyanotic color) and glandular cells, which will later turn into the placenta, and at this time provide the embryo with oxygen and substances necessary for its nutrition. As the embryo grows and the pregnancy progresses, the endometrium gradually thickens. In ultrasound, the thickness of the endometrium at 4 weeks of gestation is 20 mm on average.

[10], [11]

Breasts at the 4th week of pregnancy

Breasts at the 4th week of pregnancy continue to undergo changes. As a result of hormonal changes, its gradual reorganization to breastfeeding begins. Symmetrical growth, roughness and increased sensitivity of mammary glands are noted. There may be a slight soreness, as well as darkening of the nipples and areoles.

[12]

Belly at 4 weeks gestation

The belly does not undergo any changes at the 4th week of pregnancy, namely, it does not increase in size, because the embryo is still very tiny and the uterus is in the pelvic area. There may be minor pains of a pulling character in the lower abdomen, but they usually pass after a few days.

Ultrasound at 4 weeks of gestation

Ultrasound at 4 weeks of gestation is transvaginal and confirms an intrauterine pregnancy. It is defined as a small black circle with a diameter of several millimeters in diameter, and is called a fetal sac. Also on ultrasound in this period, you can see the dilated blood vessels in the uterus, which is the norm and is associated with the need for more active feeding of the developing embryo.

Embryo tissue at 4 weeks is still not possible to see, but by the end of this week, you can see a yolk sac on ultrasound, representing a ring in two or three millimeters. And after seven days on this ringlet, it will be possible to see a tiny embryo, which receives the necessary substances from the yolk sac.

Intensively continues to work the yellow body of pregnancy: 

• increasing in size, provides nutrients to the embryo, until the placenta is formed, 
• and also continues the production necessary for the maintenance and progression of pregnancy - the hormone progesterone.

Ultrasound at 4 weeks of gestation is rare, when carried out at an early stage, it is also possible to confirm or exclude an ectopic pregnancy or a bladder drift in order to react in time and prevent undesirable consequences.

Feeling at 4 weeks pregnant

The state of health at the 4th week of pregnancy is characterized by the instability of the emotional background - increased irritability, tearfulness; the appearance of disorders of the digestive tract - nausea, vomiting; minor pulling pains in the lower abdomen and / or in the lumbar region. In general, I feel at the 4th week of pregnancy, many women feel fine.

Abdominal pain at 4 weeks of gestation

If the stomach or belly hurts on 4 week of pregnancy, this symptom can be some reasons. The abdomen at 4 weeks of pregnancy can be ill and normal, the pains are pulling, not accompanied by any bloody discharge, does not increase their intensity and quickly pass. Abdominal pain at week 4 may also indicate a pathological process: 

• diseases of urinary organs (pyelonephritis, cystitis), but in such cases, the pain is often associated with urination disorder and temperature rise, 
• disruption of the intestine in the form of constipation, flatulence, 
• perhaps the existing pregnancy is ectopic, so as the embryo grows and the uterine tube stretches, pain develops, 
• pain can indicate a threat of miscarriage or a frozen pregnancy, especially if they are intensified and accompanied by bloody discharge, 
• possible inflammatory processes in the organs of the abdominal cavity (for example, appendicitis).

Given the large number of causes that can cause abdominal pain, especially at 4 weeks of gestation, it is better to consult a doctor to prevent unwanted effects on a woman and the course of pregnancy.

[13], [14]

Why pulls the stomach at 4 weeks gestation?

Often pulls the stomach at 4 weeks of pregnancy due to changes that occur in the female body. Namely, there is a displacement of the pelvic organs, stretching of the muscle fibers and ligaments, which contributes to the occurrence of pulling pains in the abdomen.

Also pull the belly can: 

• after doing any physical exercises, 
• at threat of a miscarriage, 
• with ectopic pregnancy, 
• as a result of pathological processes in internal organs.

In pathological conditions, which are accompanied by pain in the abdomen, other symptoms (eg, spotting, fever, urination, pain, etc.) are often noted, which requires immediate medical attention.

Allocations at 4 weeks gestation

Allocations on the 4th week of pregnancy can be thicker than usual, transparent or with a whitish shade, without smell and do not cause discomfort in a woman. Possible light brown discharge, especially at the beginning of 4 weeks, when implantation finally takes place, usually such excretions do not disturb, do not smell and disappear after a few days.

[15], [16], [17], [18], [19],

Brown discharge at 4 weeks of gestation

Brown discharge at 4 weeks may be the norm, especially if they have a light tint, are not accompanied by a smell and do not bring discomfort to a woman. Such discharges are associated with the hormonal rearrangement of the female body, as well as with the completion of implantation of the embryo in the endometrium of the uterus, and pass in a few days. Allocations of dark brown color should alert, especially if they are accompanied by pains in the abdomen and / or lower back, increase in volume, get an unpleasant smell. Such discharges can speak of frozen or ectopic pregnancy, erosion of the cervix, the threat of miscarriage or the presence of a bacterial sex infection, which requires an immediate appeal to a specialist.

[20]

Bloody discharge at 4 weeks gestation

Bloody discharge at 4 weeks of pregnancy requires special attention. Bloody discharge can be the result of: 

• ectopic pregnancy, 
• sexual intercourse, 
• gynecological examination (secretions are minor, usually not dangerous), 
• frozen pregnancy (spotting sparse and spotting blood), 
• erosion of the cervix.

The appearance of bloody discharge at 4 weeks of pregnancy is the reason for going to the gynecologist to determine the cause of such secretions and, if necessary, to undergo appropriate therapy.

[21]

Back pain at week 4 of pregnancy

The lower back hurts at the 4th week of pregnancy due to various reasons, such as physiological reconstruction of the osteo-ligament apparatus or because of the presence of some pathological process in the body. Causes of back pain at week 4 may include: 

• Normally, due to changes in the osteochondral apparatus, when the hormone relaxin is produced, which makes the connective tissues loose, as a result of which their extensibility increases, as well as the mobility of the pelvic bones. Thus, the body is preparing for the forthcoming birth. 
• Excess weight, which is gradually gaining a woman during pregnancy. 
• The pathology of the spine, which is even before pregnancy (scoliosis, osteochondrosis). 
• Inflammatory processes in the kidneys (pyelonephritis). Usually, with kidney diseases, there are disorders of urination and fever. 

The threat of miscarriage can be accompanied by low back pain and spotting.

Thus, in the case of lumbar pains, the intensity of which does not pass, but increases and further symptoms are noted, it is necessary to urgently contact the doctor to promptly identify the cause and prevent unwanted complications.

[22], [23], [24]

Temperature at 4 weeks gestation

Often the temperature at the 4th week of pregnancy rises to a low-grade figure, namely to 37.3 ° C. This temperature can be observed both in the early term and throughout the pregnancy. In the absence of any other symptoms (for example, headache, rhinitis, etc.), this temperature is regarded as the norm, due to: 

• changes in the metabolism towards its acceleration, 
• changes in the hormonal background - increased production of the hormone progesterone, which affects the center of thermoregulation in the brain, 
• decrease immunity, so that the woman's organism does not reject the alien embryo for him.

The increase in temperature at 4 weeks of pregnancy to 38 ° and above may be due to any disease: 

• ORVI or the flu, 
• inflammatory diseases of internal organs (for example, pneumonia, pyelonephritis).

Self-medication at high temperature to be categorically contraindicated, tk. This can seriously harm both the health of the woman and the health of the embryo, because This week the bodies and systems, laid down in the third week, are developing intensively. May be noted in the aftermath of malformations of certain organs, mental retardation, etc. In addition to such complications, high temperature can provoke abortion. Therefore, you should treat your condition very carefully, especially in conditions of high temperature and contact the doctor in a timely manner.

Ectopic pregnancy at week 4

Ectopic pregnancy at week 4 is characterized by the same symptoms as the uterus. It is also noted: 

• delay in menstruation, 
• emotional breakdown, 
• the change in the sensitivity of the mammary glands and their increase, 
• possibly the appearance of nausea, increased salivation, 
• change in taste and intolerance to certain odors, 
• increased basal temperature, etc.

The cause of the occurrence of an ectopic pregnancy is the inability of a fertilized egg to enter the uterine cavity, due to a violation of the patency of the fallopian tubes, as a result of which the egg is implanted in the fallopian tube. The cause of the violation of passage of the fallopian tubes can be: 

• inflammatory processes in the ovaries and fallopian tubes, both as a result of nonspecific infections (for example, after an abortion), and specific ones that are transmitted through the genital tract (chlamydia, gonorrhea, trichomoniasis, etc.) 
• operations on the organs of the abdominal cavity and organs of the small pelvis, leading to an adhesive process, 
• congenital underdevelopment of the fallopian tubes, 
• hormonal disorders in women.

The risk of an ectopic pregnancy occurs: 

• with increasing age (over 35 years), 
• in women with the presence of endometriosis and with chronic diseases of the genital organs, 
• from smokers, 
• in the presence of an intrauterine device, 
• with congenital anomalies of the uterus and its tubes, 
• tumors of internal organs.

It is almost impossible to determine ectopic pregnancy independently. Ectopic pregnancy is extremely dangerous for a woman's life. Approximately in the fourth to sixth weeks of pregnancy the villi of the embryo germinate the uterine tube, the embryo intensively develops and the uterine tube may break, which is accompanied by: 

• bleeding into the abdominal cavity (if a large vessel is damaged, then this is extremely dangerous because of the large loss of blood), 
• sharp cramping pain in the lower abdomen, 
• dizziness, 
• pallor of the skin, 
• loss of consciousness, etc.

In some situations there is a rupture not of the uterine tube, but of the fetal egg. In this case, the expulsion of the fetal egg occurs not in the uterus, but in the abdominal cavity - tubal abortion. With this abortion, there is also dizziness, acute abdominal pain, weakness, but the symptomatology develops more slowly than in the case of rupture of the tube. There may come an imaginary well-being, the code all the symptoms disappear, and the woman thinks that everything has returned to normal, but the bleeding continues into the abdominal cavity and this is very dangerous. With a slight suspicion of ectopic pregnancy, and also if a woman is at risk for developing an ectopic pregnancy, it is a reason to go to a doctor's consultation and be examined.

[25]

Miscarriage at the 4th week of pregnancy

Miscarriage at the 4 th week of pregnancy usually begins with minor bloody discharge gradually increasing. The color of bloody discharge can be from scarlet to dark red. Often such discharges are accompanied by spasmodic pain in the lower abdomen, as well as back pain, sometimes body temperature may rise. Bloody discharge may contain tissue particles.

Miscarriage occurs for some time, from several hours to several days. In this case, spotting can be minor, but last more than a few days.

The emergence of miscarriage in the early stages of pregnancy is often associated with genetic breakdown in the embryo, incompatible with life. Also, miscarriage at an early age can occur as a result of any illness in a woman, inadequate exercise, use of drugs, alcohol, etc.

When bloody discharge occurs, accompanied by pain, weakness and increased temperature, you should immediately contact a doctor.

Bleeding at week 4 of pregnancy

Bleeding at the 4th week of pregnancy should be seriously alarmed, and is an excuse for consulting a doctor. Short bleeding, in the form of a few drops, not accompanied by pain in the abdomen and lower back, an increase in temperature should not be particularly troublesome, this may be noted: 

• after sexual intercourse, 
• after a gynecological examination.

Abundant bleeding, not stopping, but on the contrary increasing, containing tissue particles and accompanied by deterioration of the general condition of a woman - weakness, pale skin, pain in the lower abdomen and / or lower back, is a dangerous condition and requires immediate medical attention. Bleeding of this nature can be due to spontaneous abortion and complicated ectopic pregnancy.

[26], [27]

Monthly at week 4 of pregnancy

Monthly for 4 weeks of pregnancy, as a rule, are not observed. But in the early stages of pregnancy - the first weeks or even months, when only the placenta is developing, there may be a slight allocation of hormones that suppress the menstrual function and at the appropriate time, possibly the appearance of minor bloody discharge. In addition, the allocation similar to the monthly on the 4th week of pregnancy may be due to: 

• ectopic pregnancy, 
• frozen pregnancy, 
• spontaneous miscarriage, 
• erosion of the cervix, 
• after a gynecological examination or sexual intercourse.

The emergence of excretions, reminiscent of the monthly, is the reason for the visit to the gynecologist for examination and further tactics, in order to prevent undesirable consequences for the health of women and the embryo.

Toxicosis at 4 weeks of pregnancy

Toxicosis at the 4th week of pregnancy is not rare, but not mandatory. The emergence of early toxicosis is associated with a number of reasons: 

• with a change in the hormonal background of a woman, 
• with diseases of the gastrointestinal tract, 
• with the ingestion into the blood of the pregnant metabolic products of the embryo that cause intoxication in her body, 
• and there is a hereditary predisposition (when the mother of a pregnant woman suffered from toxicosis, it is most likely that her daughter will also have toxicosis).

Often, early toxicosis is noted until the placenta (usually up to twelve weeks) is formed, which will protect the woman's body from the products of the embryo exchange.

Most often, early toxicosis is noted during the first pregnancy, in the case of subsequent pregnancies, symptoms of toxicosis decrease or absent.

Toxicosis at the 4th week of pregnancy is most often manifested by nausea, sometimes vomiting, as well as increased salivation, intolerance to individual foods and / or odors.

A mild toxemia is accompanied by morning sickness, after breakfast or nausea, which can be observed half a day and sometimes accompanied by vomiting. Severe toxicosis is characterized by nausea throughout the day and night, and is accompanied by repeated vomiting, which requires medical attention to avoid dehydration and further complications of pregnancy.

To facilitate the manifestations of toxicosis will help - breakfast solid food, without getting out of bed; fractional food throughout the day with high-calorie food (not greasy); use of chilled foods and a sufficient amount of liquid.

Frozen pregnancy at 4 weeks old

Frozen pregnancy at 4 weeks occurs for various reasons, namely: 

• as a result of genetic disorders in the embryo, which are not compatible with life, 
• with hormonal disorders occurring in the body of a woman as a result of some disease or drug use, 
• the presence of bacterial genital infections (gonorrhea, chlamydia, herpes, etc.) 
• acute viral infections (influenza, etc.), 
• alcohol abuse, smoking, 
• prolonged exposure to the sun, 
• Rhesus-conflict, 
• frequent abortions, 
• regular physical and nervous overstrain.

It is difficult to suspect a frozen pregnancy on its own, as pregnancy symptoms can often be noted. But it should alert: 

• the appearance of suppositories, 
• disappearance of signs of toxicosis, 
• severe pain in the lower abdomen and / or lower back, 
• a causal increase in body temperature.

In case of occurrence of such symptoms consultation and examination is necessary at the expert who will spend, first of all, US and will be defined by the diagnosis.

Cold at 4 weeks of pregnancy

Colds at 4 weeks of pregnancy can occur in many women, especially in conditions of reduced immunity in the early period. A cold, in which there is no temperature, chills are not terrible. But when there is a high temperature, above 38 ° C, chills, pallor of the skin, i.e. Symptoms of intoxication, the cold becomes dangerous both for the pregnant (complications, for example, pneumonia), and for the embryo (disruption of its development, fading, miscarriage). In order not to expose a pregnant woman to colds, you need to perform a set of simple preventive measures: 

• In the epidemic period of acute viral infections, try not to visit places with a large number of people, 
• if there is a cold in the environment of a pregnant patient, especially in an acute period, it is desirable to isolate it for several days, 
• use saline solutions in the nasal passages in the form of drops or spray (Humor, Aqua-Maris, Quix), 
• at the location of the pregnant woman, frequent airing of the premises is necessary, 
• wakefulness and sleep should be performed, 
• frequent walks in the fresh air, 
• a balanced and balanced diet with a high content of vegetables and fruits, microelements, 
• if necessary, the use of vitamins for pregnant women (Vitrum Prenatal, Pregnavit).

If nevertheless a pregnant woman has a cold, especially with fever, it is recommended to consult a doctor for appropriate recommendations. Self-medication should not be dealt with, because this can adversely affect the development of the embryo, because not all medicines can be taken during pregnancy.

Nausea at the 4th week of pregnancy

Nausea at 4 weeks of pregnancy may occur more than half of women. Most often it occurs in the morning on an empty stomach and disappears after eating, so it is recommended not to get out of bed to eat a piece of bread or a biscuit, to lie down for about fifteen minutes, and to get up in bulk. Sometimes, nausea can disturb half a day, and in severe cases (which is rare) throughout the day and accompanied by vomiting. To reduce the severity of nausea and eliminate it, it is recommended: 

• take food in small portions and often, 
• it is better to eat food in a refrigerated state, 
• eat more hard food, 
• start breakfast in bed, 
• food should be high-calorie, but not greasy, 
• drink enough non-carbonated water, 
• rest and enough to sleep, 
• to walk outside.
• These simple measures will help the pregnant woman to reduce the severity of nausea and eliminate it.

Interruption of pregnancy at 4 weeks

Termination of pregnancy at 4 weeks should be done under the supervision of a doctor, it is dangerous for the woman's health to deal with this matter on her own. Since only a doctor can assess the condition of a woman, choose a method of abortion and control the entire process of interruption. In the early period, as a rule, a drug abortion is performed.

Medical abortion is the safest method of medical termination of pregnancy in the early term. When carrying out medical abortion apply such drugs - Mytholian, Mifepreks, Pencrofton, Mefigin, Mifepriston. Such abortion is carried out in several stages: 

• at the initial stage, an examination, ultrasound and necessary laboratory blood tests are performed, after which they prescribe the drug and monitor the woman for one to two hours, 
• in the next stage, after 36-48 hours after the use of the drug, prostaglandins are prescribed, after which miscarriage occurs and is manifested by bloody discharge.

After the miscarriage, another ultrasound is performed, which confirms the complete absence of the fetal egg in the uterine cavity and is performed ten to fourteen days later.

Advantages of drug abortion are: 

• minimum or absence of complications and proceeds as usual monthly, 
• no need to be hospitalized, i.e. You can lead an active lifestyle, 
• absence of instrumental intervention in the uterine cavity, which reduces the risk of infection, 
• psychologically better tolerated.

Sex at 4 weeks of pregnancy

Sex at 4 weeks of pregnancy is not a contraindication, and perhaps vice versa will be very necessary for a woman, since at this stage, the libido rises. It is necessary to remember about observance of intimate hygiene of both partners both before, and after sex. Contraindication to having sex at week 4 is bacterial sexual infection in the partner, as well as the presence of a woman's bloody discharge, abdominal pain and / or lower back.

Alcohol at the 4th week of pregnancy

Alcohol at the 4th week of pregnancy is absolutely contraindicated, because in this period there is an intensive development of all organs and systems. Alcohol has a toxic effect on the body, both women and the embryo. And the consequences of drinking alcohol, especially during the formation of organs, can be deplorable (the birth of a sick child).

[28], [29]

Nutrition at the 4th week of pregnancy

Nutrition at 4 weeks of pregnancy should be full and balanced. Food should be high-calorie, but not fatty and fried, steamed, boiled and must contain a sufficient amount of micro- and macro elements, fruits and vegetables, fermented milk products (kefir, cottage cheese, milk, yogurt), low-fat meat and fish.

Antibiotics at week 4 of pregnancy

Antibiotics at 4 weeks of pregnancy are contraindicated, since they are dangerous for the embryo, especially in this period, when there is an intensive development of all organs and systems. Unreasonable intake of antibiotics at week 4 may cause the malformation of an organ in a future child.

There are certain indications for the use of antibiotics, which are prescribed only by a doctor. Antibiotics can be used under the supervision of a doctor in the following cases: with pyelonephritis, pneumonia and other purulent inflammations of internal organs, sepsis, bacterial infections. With colds and flu, antibiotics are not used, because they act on bacteria, and influenza causes viruses, this must be remembered.

There are antibiotics that are allowed for use during pregnancy, but 4 weeks are not the best time to use them.

[30], [31], [32], [33], [34], [35]

Flight 4 weeks pregnant

Flight at 4 weeks of pregnancy can be contraindicated. As the body of a woman adapts to new changes associated with hormonal changes. Also, the phenomenon of toxicosis can interfere with the flight, especially if the toxicosis is severe.

Contraindications to flight in the early period are: 

• repeated vomiting, 
• bleeding, 
• pain in the abdomen and lower back, 
• anemia,
• pregnancy, after in vitro fertilization 
• exacerbation in pregnant chronic diseases, 
• defects and diseases of the genital organs in pregnant women.

4 week of pregnancy - the term of pregnancy is better to be near the house and in the usual situation. The best time for rest with flights is the second trimester of pregnancy (from the 14th to the 28th week).
