Dangerous periods during pregnancy: how to survive them calmly. Dangerous weeks of pregnancy are not a myth, but a real phenomenon

Rhythm of life modern women It is characterized by bustle, tension, an abundance of information, people, emotions, affairs and situations. Having no particular significance for normal life, when pregnancy occurs, all these factors become important and require attention. After all, during all nine months a woman is responsible not only for herself, but also for little man growing inside her.

Any negative factors right now can lead to the most dire consequences. However, there are times when you need to be especially attentive to your health and surroundings. Such critical periods of pregnancy can be identified in any of the three trimesters.

First three months

In a woman’s pregnancy calendar, this is the period from the moment of conception until the 12th week inclusive. Nothing is noticeable externally yet; all changes occur inside the body. The fertilized egg begins to move towards the uterus and, around the seventh day, attaches to one of its walls. The mucous membrane grows around it, forming the future placenta. The entire hormonal system is being rebuilt, the main task of which is now to maintain pregnancy.

Features of the trimester

By the end of the first month, the embryo is one centimeter long. It is at this moment that the future organs of the baby begin to form, bone, muscle and cartilage tissue, circulatory and lymphatic systems are formed. In just two months, the embryo doubles in size. He develops tiny arms and legs, and his ears and nose become noticeable. By the 12th week, all organs and tissues are almost completely formed, the baby can move his fingers, open his mouth and hear sounds. True, these movements are not yet felt by the woman, because his height is only 9 cm, and his weight is approximately 10–15 grams.

The main danger of this period is the likelihood of developing defects in the embryo, which is much higher in the first trimester than in all subsequent trimesters and can lead to miscarriage.

Dangerous Weeks

The importance of the first months lies in the fact that at this time the formation of almost all the baby’s organs occurs. But it is precisely during these periods that some women may not even be aware of a change in their situation, of course, if the pregnancy was not planned, and may not change their life habits. There are several most critical periods:

1. The second week is the time when the embryo attaches, it is dangerous high probability spontaneous abortions. They can be caused by stress, high physical activity, too much leisure, developmental abnormalities or infectious and inflammatory diseases.
2. The time from the 4th to the 6th week is dangerous due to the possibility of the formation of malformations and, as a result, termination of pregnancy.
3. The end of the third trimester, namely the period from the 8th to the 12th week of pregnancy, when active formation placenta and any negative influences can interfere with its normal development. In addition to this, the body begins to intensively produce hormones and disturbances in this process can also lead to developmental abnormalities.

Precautionary measures

At this time, any infectious and inflammatory diseases pose a danger to a woman, even a common cold, which many are accustomed to suffering on their feet and at work. The use of most drugs, especially hormonal drugs, antidepressants and antibiotics, is prohibited. The use of which, in cases where it is impossible to do without medications at all, is now mandatory to be agreed with a doctor.

Even some of the herbs, such as comfrey or coltsfoot, can be dangerous.

Second three months

The period from the 13th week to the 24th is called the second trimester. Usually this is the most pleasant time, when toxicosis, fatigue and lethargy have already subsided. The body has adapted to pregnancy, and the barely visible belly does not interfere with living at its usual pace.

Features of the trimester

By the 16th week, the formation of all the baby’s organs and tissues is completed, and he begins to feed through the placenta. His height at this time is approximately 16 cm, and his weight reaches 100 grams. In another two weeks, the baby will have a skeleton with all joints, its own daily rhythm of sleep and wakefulness will be established, and hearing will become more perfect. Now mom can easily start reading fairy tales and singing songs, he hears it all perfectly. By the end of the second trimester, the baby's height is approximately 30 cm and weight is about 500 grams. He can no longer tumble freely in the uterus and constantly listens to his mother and her emotions.

Particular attention should be paid to discharge, which may become a harbinger of infection, which poses the greatest danger during this period.

Dangerous Weeks

The second three months also have their own critical periods of pregnancy, during which a woman needs to be especially careful.

The time of pregnancy is from the 16th to the 17th week of pregnancy, when any infection, including common cold, may have a negative impact on final formation baby skeleton. In addition to this, starting from the 16th week, uterine hypertonicity sometimes manifests itself.

If you are expecting a girl, then at 19–20 weeks infectious diseases may negatively affect the process of laying eggs in her body.

The time from the 18th week to the end of the second trimester, that is, up to the 24th week inclusive, represents a particular danger, since pregnancy can be complicated by the appearance of isthmic-cervical insufficiency. Due to the increasing weight of the fetus, the length of the cervix shortens and the pharynx opens. The reasons for this may be previous injuries to the cervix, for example, as a result of previous abortions.

More often, women expecting twins or triplets suffer from this pathology.

Precautionary measures

At this time, a pregnant woman should carefully monitor her diet and lifestyle. Try to avoid large crowds of people, cramped, poorly ventilated rooms and public transport. Especially if the second trimester occurred in winter period, rich in colds.

As a rule, if there is a threat of miscarriage due to increased tone or in the presence of isthmic-cervical insufficiency, the doctor prescribes strict bed rest, sometimes at home, but more often in a hospital.

Last three months

The final stage begins from the 25th week and lasts until the actual birth, that is, until the 40th week of pregnancy. A significantly larger belly prevents a woman from walking and sleeping freely, and the added pounds can cause pain in the joints and lower back. The enlarged uterus puts pressure on internal organs, causing shortness of breath, heartburn, problems with digestion and urination. Physically, this period is the most difficult.

Features of the trimester

At the 28th week, the baby’s height is approximately 35 cm, and the weight is already 1100 g. However, he does not intend to stop there. The brain continues to develop and nervous system, sense organs are improved. By the end of the third trimester, he can grow up to 50 cm and gain weight up to 3500 grams. The uterus gradually descends, and just before birth, the baby’s head also descends.

The greatest danger during this period is premature birth and the birth of a premature baby.

Dangerous Weeks

All the troubles associated with this period occur mainly in the 28th and 32nd weeks. It is at this time that premature birth can occur, caused by disruptions in hormonal background, provoking late toxicosis or cervical insufficiency.

One of the most dangerous complications This period is placental abruption. Strictly speaking, this pathology can manifest itself in any trimester, but it is during later, when all the compensatory capabilities of the body have already been exhausted, it is most difficult. Any signs of detachment serve as a reason for emergency hospitalization. If the detachment occurred immediately before or during childbirth, then either stimulation is performed labor activity, or caesarean section.

Another complication may be feto placental insufficiency resulting from previous infectious diseases. The development of this pathology causes disruption of the functions performed by the placenta. It stops supplying the baby with nutrients and oxygen, cannot cope with waste products and cannot protect the baby from adverse factors that can lead to termination of pregnancy.

Precautionary measures

Do not wait anxiously for the date prescribed by your doctor to approach. If your baby does not appear clearly on the appointed date, this does not mean that something went wrong. Avoid stressful situations, get plenty of rest, give up long trips and with increased attention take into account any changes that appear in the body.

Starting from the 34th week, the born baby is considered completely healthy. Such termination of pregnancy, a little earlier than the term, as a rule, does not pose any danger. If the doctor discovers any of the conditions that threaten the health of the mother or baby, then the woman is placed on conservation care until the birth.

Maximum attention to yourself and timely contact with a doctor for advice or help will help you avoid most threatening factors. And waiting for the birth of a son or daughter will be pleasant and happy.

A desired pregnancy is an exciting and pleasant period of life. The woman tries to act according to the doctor’s recommendations and is actively preparing for the meeting with long-awaited baby. However, unfortunately, there is always the possibility of spontaneous termination of pregnancy. Which weeks are the most dangerous for a developing baby? How should a woman behave during these periods and when should she seek help? medical assistance?

Dangerous periods during pregnancy - myth or reality?

Critical periods- This is by no means a myth, they exist. The possibility of fetal death is explained by the characteristics of the body of a particular woman and the influence negative factors environment.

The following can lead to miscarriage or the development of various pathologies in the baby:

• non-compliance with a woman's daily routine;
• hypothermia or overheating;
• taking certain medications;
• exposure to toxins, chemical substances, radiation;
• oxygen starvation of the fetus;
• improper or insufficient nutrition of a woman;
• excessive physical activity;
• endocrine diseases;
• any bacterial or viral infections;
• diseases in acute or chronic form;
• stress.

The fetus is sensitive and vulnerable during certain weeks of pregnancy. During these periods, a woman should especially carefully monitor her condition.

What dangers await pregnant women at different stages?

This article talks about typical ways to solve your issues, but each case is unique! If you want to find out from me how to solve your particular problem, ask your question. It's fast and free!

The body of a pregnant woman experiences enormous stress. Unfortunately, it is impossible to name one of the most dangerous periods of pregnancy that you need to survive in order to then calmly prepare to meet your baby. There are several critical periods, and a woman must carefully monitor her condition in order to prevent termination of pregnancy in time if it becomes likely.

There is an opinion that when carrying a baby, the days in which a woman had menstruation before conception are dangerous. In other words, such periods occur on certain few days of each month.

1st trimester

The first trimester is the most important, since at this time the fetal organs are laid and begin to form. The first dangerous period occurs at 2–3 weeks: the embryo tries to attach itself to the wall of the uterus, but is vulnerable due to the lack of a placenta, since it is just beginning to form. The woman behaves as usual, does not feel any changes in her health and may not be aware of the new life that has arisen in her. Stress, alcohol and nicotine, physical activity, and heavy lifting can cause abortion.

By the 5th week the fetus has formed spinal column and heart, and the woman is tormented by toxicosis, general malaise etc. Under the influence of these factors, the development of defects and the fading of pregnancy is possible.

Dangerous weeks of pregnancy are considered 8–12, since the formation of the placenta, which provides nutrition and protection for the baby, occurs, and the woman’s hormonal background also changes. If the placenta is malfunctioning and there are sudden changes in the body of the expectant mother, pregnancy often cannot be maintained.

2nd trimester

The time interval from 13 to 24 obstetric weeks is considered relatively safe - pregnancy proceeds safely, toxicosis stops. The laying of the organs of the embryo ends by the 16th week, it begins to receive nutrition through the placenta (see also:). However, the risk of pathologies in the fetus or the possibility of miscarriage still remains.

The fetus is susceptible to infectious diseases of a woman at any stage of pregnancy. At 16-17 weeks they can affect the development of his bone tissue. Critical weeks are considered from 18 to 22. Termination of pregnancy occurs for several reasons:

• Weakening of the cervix. Under pressure from the weight of the fetus, it opens, which provokes premature birth. The pathology is quite rare, and if expectant mother See a doctor in time, the pregnancy can be saved.
• Incorrect location of the placenta - attachment in the area of ​​the postoperative scar, presentation.
• Sexual infections. Possibility of thrush, bacterial vaginosis increases due to hormonal changes and increased vaginal discharge. Chlamydia, herpes and ureaplasmosis, transmitted through sexual contact, are dangerous.

3rd trimester

In the third trimester, the load on the expectant mother’s body increases. The pressure on the spine increases, the woman feels constant fatigue, shortness of breath, joint pain, her sleep is getting worse. Experts consider the period from 28 to 32 weeks of pregnancy to be critical.

A woman’s body is actively preparing for childbirth, and it is important that it does not begin prematurely. According to statistics, at this time the likelihood of hormonal surges increases, which provokes various complications.

A dangerous consequence of changes in hormone levels is placental abruption. This pathology can manifest itself in any trimester, but on the eve of birth, the mother’s body’s strength is already depleted, so it is difficult to stop the process. The woman is urgently hospitalized, and if the detachment occurs before childbirth, then stimulation of contractions or a caesarean section will be required.

Miscarriage in the 3rd trimester can also be caused by:

• weakening of the cervix;
• fetoplacental insufficiency, depriving the fetus nutrients and leading to hypoxia;
• abnormal amount amniotic fluid;
• late toxicosis.

Fortunately, a child born on last weeks pregnancy can be saved. However, what longer baby will be in the mother's womb, so much the better.

The period of pregnancy considered the most dangerous

Obstetricians call the first 3 months the most dangerous period of pregnancy. The possibility of interrupting it early, in contrast to the next two trimesters, is 3 times higher. The critical time is from 14 to 21 days from conception, when the embryo attaches to the wall of the uterus.

If at this time a woman is taking strong medications, intensively playing sports and generally leading her usual lifestyle, ovum may not stick. In this case, it will come out along with the blood during the next menstruation. However, such a miscarriage is considered the most painless emotionally - the woman often does not understand that a fertilized egg has been released. Also, at a period of 3 weeks there is a high risk of developing pathologies and defects in the fetus.

From 8 to 12 weeks, a sharp change in the concentration of hormones occurs in the body of the expectant mother. If the body's functioning is disrupted, some organs of the embryo may be underdeveloped or the pregnancy may be terminated.

Experts believe that the most dangerous periods are associated not only with physiology and factors influencing a woman from the outside, but also with her psychological state. If she had one or more miscarriages during approximately the same period, then for her personally it is critical. Being pregnant again, the woman worries and is afraid of a repetition of the situation, which provokes severe stress. Sometimes in such cases hospitalization is practiced.

How to behave during critical periods of pregnancy?

The presence of such a thing as critical periods is not a reason for every woman to think about the possible loss of a child. Many people carry a baby from first to last day without any complications. There is no point in waiting with horror for the onset of dangerous periods; during these weeks you should just be a little more attentive to yourself:

• avoid stress;
• exclude intense physical activity;
• rest more often and sleep 8 hours a day;
• do not travel long distances.

If a woman has no health complaints, she or her husband have no genetic diseases, there is no reason to worry. At the end of 12 weeks, the gynecologist will have data from the first ultrasound, which will allow him to determine the condition of the fetus. This will help him correct further actions, prescribe treatment or warn the woman if she needs to be careful. The patient is only required to comply with all his instructions.

Most often, obstetricians talk about critical periods when their patients are faced with the problem of miscarriage - multiple terminations of pregnancy. In this case, women need to give up intimate contacts, physical activity and more rest during the dangerous weeks, as well as during the previous miscarriage and the days of the expected menstruation.

In what cases should you call a doctor immediately?

If during dangerous periods of pregnancy a woman feels abdominal pain and notices discharge from the genitals unusual color, water leakage, she needs to go to the hospital. Alarming symptoms may vary depending on the period. In the 1st trimester, signs of a possible termination of pregnancy will be:

• nagging pain in the lower abdomen;
• brown or red discharge;
• cessation of nausea and breast engorgement.

The woman needs to call an ambulance, take a No-Shpa or Drotaverine tablet and put in a suppository with papaverine. While waiting for specialists, you need to take a position in which you do not feel discomfort.

In the 2nd and early 3rd trimesters, concern should arise from:

• bloody issues;
• leakage of amniotic fluid (determined by a pharmacy test);
• cramping pain every 20–30 minutes in the lower back or lower abdomen;
• fading or active movements baby;
• stitching sensation in the vagina.

With such symptoms, the pregnant woman is immediately hospitalized. If the fetus is alive, developing normally and there is no threat to the mother’s life, doctors will fight to save the baby and, if possible, preserve the pregnancy. If a critical situation arises in the last weeks of pregnancy, specialists hospitalize the mother and use drugs to develop his lungs premature baby so that he is born healthy.

It has been established that these terms are more or less common for women included in certain risk groups. For each critical period, the most characteristic causes of termination of pregnancy can be identified.

I trimester(first three and a half months of pregnancy). The first critical period occurs in the 2-3rd weeks of pregnancy, when a woman may not yet suspect that development is beginning in her body. new life. At this time, implantation of the fertilized egg occurs, i.e. its penetration into the uterine mucosa. The implantation process may be disrupted:

• with abnormalities in the structure of the uterus (infantilism, bicornuate or saddle-shaped uterus, the presence of a septum in the uterine cavity;
• for endometrial injuries as a result of induced abortions and inflammatory diseases(chronic endometritis);
• in the presence of uterine fibroids;
• with a scar on the uterus after caesarean section and other operations.

Another reason for termination of pregnancy in the earliest stages is chromosomal and genetic abnormalities in the development of the embryo. A kind of natural selection of future offspring occurs. As a rule, a woman does not yet have time to find out about her pregnancy - her next period comes, and psychological trauma manages to be avoided.

The next critical period is 8-12 weeks of pregnancy. During this period, the placenta begins to develop, and the main reason for interruption during this period is hormonal disorders.

II trimester. The critical period of 18-22 weeks of pregnancy is the time of active growth of the uterus. At this stage, abnormalities in the location of the placenta pose a danger ( low attachment and presentation) and isthmic-cervical insufficiency. During these periods, the main cause of interruption is sexually transmitted infectious diseases. If in earlier stages of pregnancy infectious agents (chlamydia, toxoplasma, herpes viruses, as well as cytomegaly and rubella) can lead to severe fetal malformations, then in the second trimester of pregnancy they primarily lead to dysfunction of the placenta and cause infection of the membranes , premature effusion water and miscarriage.

During pregnancy, the cervix serves as a kind of “constipation” that holds the pregnancy in the uterine cavity. Isthmic-cervical insufficiency is a pathological condition of the cervix in which it is unable to perform this function. Under the influence of gravity, the fertilized egg gradually descends, the cervix dilates and a miscarriage occurs. To eliminate isthmic-cervical insufficiency, it is necessary to apply a suture to the cervix before the critical period.

III trimester. The next stage of intensive growth of the fetus and uterus occurs at 28-32 weeks. Disruption of pregnancy development during these periods can cause complications such as late gestosis, placental insufficiency and placental abruption. These conditions can lead to antenatal (before birth) fetal death.

Often, multiple pregnancies are terminated prematurely, at the end of the second - beginning of the third trimester.

Children born at 28-32 weeks are extremely premature and require a lot of effort, money and special equipment for nursing.

Doctors usually talk about critical periods when they are faced with habitual miscarriage (i.e., with repeated spontaneous interruption pregnancy). Women suffering from habitual miscarriage should be especially careful during the described critical periods, as well as on the days of expected menstruation and during periods when previous pregnancy terminations occurred: to exclude serious physical activity, intimacy, sport exercises, try to protect yourself from nervous tension. In some cases, during critical periods, it is better for a woman to be in obstetric hospital, where doctors will be able to prevent and treat these complications, and, if necessary, provide emergency assistance.

Have a safe pregnancy!

Waiting for the birth of a baby is considered a rather exciting period of life for every patient. This time is filled with pleasant anticipation and efforts to prepare a dowry for the baby. But in addition to pleasant anticipation, there are always some risks of spontaneous interruption, spontaneous miscarriage or premature delivery. Many obstetricians and gynecologists warn patients that the most dangerous weeks of pregnancy are in the first trimester. Exactly at given time Most often, interruptions and miscarriages occur. What dangers await mommy on initial stage pregnancy, and what to do if a threat appears?

The support of a loving spouse is important

When a mother learns about her impending motherhood, she begins to pay much more attention to her health and lifestyle. more attention so that the baby is born strong and healthy. But during the dangerous weeks of pregnancy, you need to be much more careful than usual and pay much more attention to yourself. Negative factors such as poor environment, unhealthy diet or frequent stressful situations and psycho-emotional overloads - only harm a woman, and if she also catches some kind of infection, then this can even lead to intrauterine death fetus or abortion.

The first trimester is the most dangerous stages gestation, because the probability of miscarriage at this time increases threefold than in the remaining weeks of gestation. It is during the first trimester that pregnant women begin to lay down the intraorganic structures and systems of the fetus. In the third obstetric week, the fertilized egg is implanted into the endometrial layer, after which it continues normal development. After this, the rudiments of the umbilical cord, placental structures and amniotic sac begin to form.

By the fifth week, according to obstetric calculations, the baby’s heart tissue and spine begin to form. Usually at this time toxicosis begins, weakness and other ailments are observed. If there are unfavorable factors, then under their influence the formation of defects in fetal development, for example, in cardiovascular structures or the brain, can occur.

The most dangerous are:

• The first days of the third week, it is at this time that the embryo is implanted into the uterine wall.
• The period from 8 to 12 weeks, when dramatic changes occur in the hormonal background of pregnant women, and sudden disruptions in hormonal structures can provoke extremely negative consequences.

Except natural factors, typical for pregnancy, there are also pathological conditions that can lead to an extremely unfavorable outcome of pregnancy. These include factors such as medications, infections, and x-ray exposure. About a quarter of all successfully fertilized eggs cannot implant into the uterine endometrium and die, leaving the uterus along with menstruation. Sometimes a woman does not even realize that she has had a miscarriage.

Therefore, the first trimester is very important for the future baby and the mother herself, so a pregnant woman needs to avoid all sorts of negative factors, this is the only way to avoid negative consequences. By the way, by this time the baby reaches about 6 cm.

Causes of anxiety

If you feel unwell, you should consult your doctor

There are many reasons for anxiety in the first trimester. One of these is the patient’s ignorance of the presence of pregnancy in the first weeks. It is especially dangerous if the patient takes medications, not knowing that she was pregnant. IN similar situations Additional examination will be required when registering with an obstetrician to exclude possible fetal pathologies.

Large-scale hormonal changes also threaten the baby and pregnancy as a whole. Such hormonal changes are fraught with the development of susceptibility to pathologies of a viral nature, which ultimately leads to the danger of pathologies, including the death of the child. Moreover, if the mother takes any medications, then they may also not affect the formation of the baby in the best possible way, calling various kinds deviations in its development.

There are a lot of hidden and obvious dangers in the first trimester, but almost all of them can be successfully prevented if the pregnant woman herself follows certain rules. The real threat to the child comes from viral and cold infections, especially at the initial stage of fetal formation.

Cold

According to experts, the mother’s colds in the first weeks of pregnancy can have the most unpredictable results. They can provoke the most tragic consequences in the formation and development of the fetus, especially when the pathology is in an advanced state or if it is not treated correctly. To the category of the most dangerous pathologies include ARVI and various strains of influenza. If they are not treated, they leak into the fetal tissue and provoke various anomalies, which most often lead to fetal death at the stage intrauterine development. This is due to the fact that in the first weeks the baby is not yet protected placental barrier, therefore he experiences the harmful effects to the fullest.

After the first stage, for example, during pregnancy in the second trimester, if the mother catches a viral disease, then it will no longer be able to directly affect the fetus. Although even in this situation there is a risk of developing fetoplacental insufficiency. This pathology leads to disruption of all placental functions, which leads to fetal hypoxia or abortion. With prolonged hypoxia of the fetus, slow development occurs, the activity of its main functions and intraorganic systems is disrupted.

In addition to ARVI and influenza variations, pathologies such as pneumonia or bronchitis are considered critical for the baby. These pathologies are fraught premature departure water or intrauterine bleeding. The consequences of such conditions are various damage to the child’s nervous system structures. When pneumonia or bronchitis is advanced, the blood flow of the placenta is disrupted, which is fraught with the same fetal hypoxia.

Another extremely dangerous pathological condition for the mother and the fetus growing inside her is rubella. The characteristic symptoms of this pathology are a hyperthermic reaction with a runny nose and severe cough, as well as noticeable swelling of the lymph node structures.

What you need to know

Therefore, in order to eliminate possible risks, it is recommended to take preventive measures. To do this, even before the girl becomes pregnant, i.e. at the planning stage, she already needs to begin preventive measures:

• Drink vitamin complexes to increase immune strength;
• It is necessary to avoid places with large crowds of people, especially when any epidemic is raging;
• If the patient is already carrying a baby, then it is recommended to use preparations with sea water to treat the nose;
• Also during the epidemic season it is recommended to wear special protective masks, changing them more often;
• Also, mommy needs to constantly keep her legs and body warm, because hypothermia is extremely contraindicated for pregnant women;
• And after staying in places where there are large crowds of people, it is necessary to rinse the nasal cavities and gargle thoroughly so that possible viral agents die and cannot provoke the disease.

The consequences of a cold for a baby can be very dire, so it is extremely important that the mother takes all measures to prevent influenza and ARVI infections.

Temperature

It is very dangerous to self-medicate

With colds and flu, pregnant women may experience hyperthermic or hypothermic conditions. Sometimes similar phenomena are considered only as characteristics of the patient’s body. Although most often such thermodynamic changes pose a serious threat to the fetus, especially if sharp changes are observed in the first weeks of gestation. The situations in which temperature changes occur may vary. If hyperthermia does not exceed 37°C in the first month of pregnancy, then this phenomenon should not seriously frighten the girl. This condition is often associated with hormonal changes, but if there are other symptoms indicating the development of a cold infection, it is necessary to take measures to treat the pathology.

If the thermodynamic indicators have risen above 37 degrees, for example, 37.5, and it does not go astray, then you should definitely go to an obstetrician-gynecologist. Such a sign may indicate the presence of an ectopic pregnancy, which is extremely dangerous for a woman and sometimes ends in death. If the temperature rises above 38 degrees, then this is a real threat to the baby. It is especially dangerous if such a temperature is not eliminated by taking antipyretic drugs.

Such a high and long-lasting temperature in the weeks of the first trimester is dangerous due to serious nervous system disorders, which are manifested by muscle hypotomy, disturbances in mental development, syndactyly or microcephaly, various developmental defects or miscarriage, etc. Hyperthermia negatively affects the baby and the placenta, because it promotes thrombus formation.

In addition, hyperthermic conditions provoke in pregnant women uterine contractions, which is fraught with termination of pregnancy due to involuntary rejection of the fertilized egg. Therefore, during the weeks of the first trimester, a woman should avoid visiting infrared cabins, saunas or baths to prevent overheating. When a pregnant woman is exposed to ultraviolet or heat, the patient’s body temperature increases, which is categorically unacceptable for a weak fetus that is not yet protected by the placenta. If a pregnant woman’s temperature rises by at least one and a half degrees during an 8-hour period, this leads to negative influence for the development of the baby.

It is considered normal if the temperature is 37.2°C in the first weeks of gestation. It’s just that serious changes occur in the patient’s body during this period, which are accompanied by minor hyperthermic reactions. But at the same time, the patient must have no signs of any infections or inflammatory processes. Moreover, such an increase in indicators is considered normal only during the first trimester. Subsequently, it drops to the standard 36.6.

Dangers by week

So, doctors warn that the most dangerous period of pregnancy is the first trimester (up to 12 weeks), when the risk of miscarriage triples. The danger exists due to the fact that at this time the very fact of conception occurs, and then the baby’s internal structures are actively laid down and begin to form.

1. At the beginning of 3 obstetric week the embryo is implanted into the uterine endometrium. If you don’t take care at this time, something irreparable can happen and the fetus will not take root, but will die and come out with menstruation.
2. The vertebral structures and heart are formed by 5 weeks.
3. In the sixth week, the risk of developing various types of fetal defects increases. Under the influence of unfavorable factors, in a 3-7 week period, it may develop heart defect, but brain defects can develop as early as 2 weeks of pregnancy.
4. In the period from 8 to 12 weeks, rapid hormonal changes occur, during which the production of androgens increases and the production of estrogen hormones decreases. Such a difference is dangerous due to fading fetal development or a miscarriage.

According to statistics, about 25% of fertilized eggs are never implanted, die and are released with menstrual blood, and the woman does not even realize that she was pregnant.

Dangerous time with IVF

If a girl could not conceive for a long time and became pregnant only with the help of in vitro fertilization, then there is a high probability of having twins. And when carrying two children, all risks double. The time of the first weeks is especially dangerous, when the likelihood of interruption seriously increases, so girls after IVF are prescribed hormonal agents. Sometimes factors that prevent a girl from conceiving in a natural way, can negatively affect the development of crumbs from an artificially fertilized and transplanted cell.

The most dangerous during IVF are the first weeks after embryo transfer. After all, these days it must be properly fixed in the uterine body, the placental tissues need to fully develop. What makes the situation worse is that the girl takes hormonal drugs, conception takes place in a non-standard way, through the transfer of a fertilized egg, and sometimes itself the immune system rejects the baby, actively producing antibodies. As a result of the influence of these negative factors in the first weeks after in vitro fertilization, the risks of bleeding and spontaneous abortion increase.

Each trimester has dangerous periods of gestation, but the first is considered the most alarming, because at this stage conception and implantation itself occur, systems and intraorganic structures of the baby are laid. The slightest negative impact at this stage it can provoke fetal defects, freezing or miscarriage. To protect yourself from possible dangers, the patient is advised to monitor her own well-being as closely as possible, because timely, qualified assistance will prolong pregnancy and save the baby’s life.

It is generally accepted that pregnancy is natural process, honed by nature and not associated with dangers. Indeed, pregnancy is not a disease, but special condition body. Unfortunately, expectant mother Nowadays, we are surrounded by stress, poor environment, and poor quality food. Therefore, it is important to know which stages of pregnancy are most dangerous, and how to protect yourself during this time.

First trimester

The most dangerous period Pregnancy is considered to be the first trimester. In the first three months there is a huge leap in development. The egg is fertilized and turns into an embryo. It moves through the tubes and attaches to the wall of the uterus; its organs are laid down and formed. In the early stages, the embryo is most vulnerable, because the placenta, which protects it from external influences, will be formed only by the middle of the first trimester.

Ectopic pregnancy

As the name suggests, an ectopic pregnancy is a pregnancy outside the uterine cavity. It can be tubal, ovarian and abdominal. Alas, Lately this pathology occurs quite often in women.

Diagnosing an ectopic pregnancy in the early stages is quite difficult. The first symptoms begin to appear when the fallopian tube is stretched. This usually happens within 2-3 weeks. One of the most reliable ways to diagnose this pathology is ultrasound. Some experts believe that ultrasound in the early stages is dangerous, however, in the case ectopic pregnancy the benefits undoubtedly outweigh the possible risks.

The most dangerous period of ectopic pregnancy is considered to be 5-8 weeks. By this time oviduct, under the pressure of the growing fertilized egg, ruptures. The rupture is accompanied by severe pain and internal bleeding, in some cases fainting and tachycardia are possible. If a woman begins to bleed, call an ambulance immediately and go to the hospital

Dangerous periods of the first trimester of pregnancy

The first critical period occurs at 2-3 weeks. It is typical that at this stage, most women do not yet suspect that they are pregnant, and therefore do not pay due attention to their health.
