1 week: what happens in a woman's body.

As already mentioned, there is still no actual pregnancy at this time. All changes that occur in the female body correspond to the normal menstrual cycle. So, 1 week of pregnancy begins with the fact that on the 1st day of menstruation, the pituitary gland secretes follicle-stimulating hormone (FSH), under the influence of which a follicle begins to develop on the ovary. In the blood of a woman, the concentration of the hormones estrogen and progesterone decreases and the amount of prostaglandin, a substance that causes uterine contractions, increases. Thanks to them, the surface of the uterus becomes loose, the layer of the endometrium exfoliates and comes out with menstrual bleeding.

After the end of menstruation, the hormonal background changes again. At the end of the first week of pregnancy, the growing follicle stimulates the production of estrogen. Under its influence, a new endometrium begins to grow in the uterus. In about ten days, he will be ready to receive a fertilized egg.

If there is a need to do an ultrasound, it is prescribed at the end of the first week of pregnancy (usually on the 5th or 6th day of the cycle), when menstrual bleeding has already stopped. The doctor will see the growing follicle and will be able to accurately predict the date of ovulation (the release of the egg from the follicle). Sexual intercourse on the eve of ovulation and on this day increases the chances of getting pregnant, so the results of an ultrasound scan will be useful for couples planning a baby.

Another way to calculate your ovulation date is to measure your basal body temperature. On the day of ovulation, it will rise sharply, the difference can be up to half a degree. Further temperature measurement will help determine the date of implantation and the fact of pregnancy.

When planning a pregnancy, pay attention to the following interesting point. Spermatozoa, which are carriers of the “girl” chromosome, are quite tenacious: they can wait for an egg up to 7 days. Spermatozoa-"boys" live not so long - from several hours to 1-2 days. If you want to try to conceive a girl, it's worth trying somewhere three or more days before ovulation. If a boy, the day of conception should fall directly on the period of ovulation.

First obstetric week of pregnancy.

The first week of menstruation can turn into the first week of pregnancy if fertilization of the egg and implantation of the fetal egg occur in this menstrual cycle. If pregnancy does not occur in this cycle, the countdown starts again in the next cycle.

Obstetric 1 week of pregnancy begins on the 1st day of the last menstruation, and 1 embryonic week is counted from the moment the egg is fertilized. That is, 1 week of pregnancy in obstetric terms precedes ovulation and fertilization. Conception usually occurs between 2 and 3 obstetric weeks.

First week of pregnancy.

Pregnancy is a complex and multi-level process, during which a whole new organism is formed from one cell. The early stages, despite the absence of symptoms, are especially important: even before conception, you should pay attention to lifestyle, adjust nutrition and be observed by a doctor. Even if there are no signs in the first week, however, the processes are happening rapidly, so the best way out for a woman suggesting pregnancy is not to be nervous, monitor your condition and wait. The calmness and well-being of the mother is the most important condition for the healthy and full development of the embryo, so take care of yourself, avoid stress and follow the doctor's recommendations. After some time, tests and studies will help you understand whether the pregnancy has definitely occurred.

Ways to determine pregnancy.

Methods to detect pregnancy at an early stage include tests, tests, and ultrasound. The choice of method depends on the term: some are indicative only at certain stages.

Ultrasound. It is usually carried out after a visit to the gynecologist if the pregnancy is confirmed. It gives accurate results, is informative and is used as one of the main diagnostic methods. The study is planned to be carried out several times to track the development of the fetus: for example, at week 6, during an ultrasound scan, you can hear the baby's heartbeat. For the first time, the gynecologist sends for this procedure only if other factors suggest pregnancy. An ultrasound examination can detect a fetal egg, assess its size and condition. It is not recommended to use ultrasound as an independent method, the procedure is carried out in combination with other methods to obtain a complete picture of what is happening. Before carrying out it is necessary to address to the gynecologist.

Pregnancy test. Many manufacturers offer affordable and easy-to-use tests that supposedly allow you to track pregnancy in the first days after conception. In fact, before the implantation of the fetal egg, this is almost impossible: such tools become informative at least a week after conception. It is then that hCG appears in the blood and urine - a hormone-marker of pregnancy. Before using the test, you must:

• make sure the current expiration date;

• follow the instructions given in the instructions.

Blood for hCG. Among all the analyzes, this one is considered reliable and at the same time accessible. The hormone hCG (human chorionic gonadotropin) begins to be produced by the female body immediately after conception, but its level becomes noticeable about a week after the implantation of the fetal egg. In the blood, its concentration is higher than in the urine, which increases the information content of the analysis. As a rule, the gynecologist sends the patient for examination if there is a possibility that she is pregnant. The analysis can be carried out independently with the help of specialized medical centers, but it is recommended to do this under the supervision of a doctor - he will be able to analyze the results and give the patient a detailed answer about her condition. Diagnosis should be done no earlier than a week after the intended conception.

The first signs of pregnancy.

In the first week of pregnancy, as a rule, there are no sensations at all: there is no stomach yet, nothing hurts, movements begin when the fetus already reaches a solid size. Women planning to conceive tend to be restless about their well-being, so they can attribute the slightest changes to the onset of pregnancy. In fact, the main signs appear from about the fourth or fifth obstetric week. These include:

• nausea in the morning;

• soreness in the chest;

• delays and lack of menstruation;

• changes in the figure (hormonal changes affect weight gain);

• changes in the genitals (swelling, color change, etc.).

The first month is considered the so-called critical period, during which the slightest influence can lead to a miscarriage, and the woman does not even know that she was pregnant. Therefore, the best thing to do in the early stages is not to be nervous and wait for signs to appear that will confirm or refute the assumptions that have appeared.

Preparation for conception.

In order for the pregnancy to be successful, it is better to prepare for it. Couples who are planning a child adjust their lifestyle so that the processes that promote conception in the body run smoothly, and the likelihood of pregnancy increases.

Visiting a gynecologist. A woman who plans to conceive a child should see a doctor regularly. The specialist will conduct an examination, tell you if there are any problems in the body that should be eliminated before conception, and give recommendations for adjusting your lifestyle. If problems are observed, the doctor will identify their cause and prescribe treatment. However, the gynecologist is not the only specialist to visit during this period. It is advisable to check health in several ways: pregnancy is a serious burden on the body. It is advisable to eliminate in advance the factors that can interfere or harm during pregnancy. A man should also be examined: the quality of spermatozoa is no less important for successful conception than the state of a woman's body.

Taking vitamins. If the body lacks nutrients, the chance of pregnancy may decrease. In the case of severe beriberi or lack of weight, menstruation, and with it ovulation, simply does not occur, that is, fertilization is impossible.

Nutrition. Problems leading to conception failure are often caused by inadequate or improper nutrition. For the onset of pregnancy, optimal weight is needed: its lack leads to inhibition of reproductive processes, an excess is harmful due to possible endocrine disorders.

Physical exercise. Hypodynamia harms all body systems, including reproductive. Moderate exercise is shown to improve metabolism, which in turn increases the likelihood of conception. Of course, excessive fanaticism, as in the case of nutrition, is inappropriate: excessive overload will only harm the body and reduce the likelihood of becoming pregnant. It is necessary to maintain a level of physical activity that does not cause serious stress to the body. This will allow:

• keep the body in good shape;

• normalize metabolism;

• strengthen muscles, which is especially important for successful gestation;

• improve sleep;

• increase libido.

The impact of physical activity on emotional well-being is also important. Stress reduces the chance of getting pregnant, and moderate activity is a good way to relieve it. It is recommended that both parents reconsider their lifestyle: both the female and male reproductive systems will benefit from healthy loads. If the couple has already practiced sports or fitness, they can be continued, but avoiding overload.

Changes in a woman's body in the first week of pregnancy.

In the first week after conception, pregnancy practically does not manifest itself in any way, but changes are already beginning to occur in the body. Over the next 9 months (40 weeks), they will become more and more noticeable: the body will begin to rebuild to ensure the full and safe development of the embryo. During pregnancy, the so-called functional systems "mother-fetus" and "mother-placenta-fetus" are formed, the ultimate goal of which is the birth of a healthy child. This mechanism is unique and has no analogues: it is not the embryo that adapts to the characteristics of the mother's body, but the body creates within itself an optimal environment for the development of the fetus. Even before conception, the processes that occur in a woman's body during the menstrual cycle are aimed at preparing suitable conditions for the fertilization of the egg. In a certain phase of the cycle, called ovulation, it is easiest to get pregnant: the cell has matured, all conditions are met.

Menstruation. The menstrual cycle of a woman is divided into several periods:

• menstruation, during which the endometrium lining the walls of the uterus separates and comes out along with the unfertilized egg. This happens if pregnancy did not occur during the previous cycle. With menstruation, the follicular phase of the ovaries begins. The dominant follicle is determined and develops, which will later give life to a mature egg;

• The ovulatory phase occurs approximately on the seventh day of the cycle and lasts about three days. During this time, the follicle reaches maturity and at the end of the phase it breaks, releasing an egg ready for fertilization;

• Ovulation is the process during which the egg leaves the follicle and descends from the ovary into the fallopian tube. This takes about an hour, the cell retains the ability to be fertilized for about another day;

• The luteal phase, which is the second half of the cycle, proceeds differently depending on whether fertilization has occurred or not. Either the implantation of a fertilized egg occurs, or the gradual death of the endometrium.

Conception. Ovulation lasts a short time, and the ability to fertilize the egg lasts only about a day or two. It is impossible to track this process on your own: some women talk about characteristic symptoms and even pain, but this is a very individual and unreliable indicator. Sometimes a characteristic discharge (cervical mucus), an increase in basal temperature can serve as a marker, but all these signs have an error and are not able to give accurate results. Nevertheless, pregnancy can also occur if sexual intercourse took place a few days before ovulation: healthy spermatozoa, entering the uterine cavity, remain viable for 3-4 days.

Implantation of the ovum. Over the next few days, under the influence of muscle contractions and mucosal cilia, the fertilized egg moves towards the exit from the fallopian tube, that is, to the uterus. Approximately in the same period, the process of crushing begins: the cells of the zygote begin to divide, but its total size does not increase, each subsequent cell becomes smaller than the previous one. Having descended into the uterus, the zygote reaches the blastocyst stage in a few days, after which it gets rid of the membrane and implants inside the endometrium - the lining of the uterine walls. Under the influence of the hormone progesterone, aimed at maintaining pregnancy, the endometrium becomes thicker and surrounds the fetal egg from all sides. Implantation allows you to protect the embryo and additionally nourish it with a secret that is produced by the endometrial glands. It usually takes several days from conception to implantation, and the countdown of the first embryonic week does not start from it, but from the moment the zygote is formed.

How to do a pregnancy test to avoid mistakes?

In order not to face such a problem as the appearance of a second dull strip on the test, girls are advised to follow the instructions for conducting the study. Firstly, testing must be carried out with the morning, the very first portion of urine, because it is in it that the maximum concentration of hCG is observed. Such a test will be the most informative and reliable. If there is a need to conduct a study at a different time of the day, then you should at least not drink a lot of liquid so as not to dilute the urine.

Use freshly collected urine for testing. It is impossible to freeze or simply cool urine before diagnosis. Dip the strip strictly to the level indicated on it, keep the test in the urine for no more than 20 seconds, and evaluate the results 5-10 minutes after the test. Sterile containers must be used to collect biomaterial. The test result should be considered positive only when two clear and bright stripes appear.

Many girls probably had a question whether it is possible to reuse a pregnancy test. Absolutely not. The indicator field of the tests used has already reacted with urine, so a second study will not cause any reaction. And if the tests used show the presence of pregnancy, then it is impossible to consider such results as reliable. It is better to use a new test.

What to do with a weak and fuzzy line on the test?

If the test gave a positive result with a weak second strip, then you should not consider it as confirmation of pregnancy. Only a doctor can give the most accurate result regarding pregnancy, because when using home express systems, there is always a risk of receiving erroneous, unreliable data, although manufacturers assure that their products are 100 percent accurate. Therefore, when a second blurry and dull strip appears, it is necessary to be examined by a gynecologist. Usually, to clarify the pathological picture, the doctor prescribes certain diagnostic procedures.

• Retesting. After the first test, it is recommended to undergo home diagnostics again after a few days (3-4).

• Ultrasound diagnostics. It allows you to detect a fetal egg inside the uterine body through a transvaginal examination. This is possible already on the 6th day of delay. If ultrasound is performed through the abdominal wall, then conception can be detected only at 7-8 weeks of gestation.

• Blood test for chorionic gonadotropin. In the blood, this hormone is found much earlier than in urine, so a blood test helps to confirm conception at the earliest possible date.

• Gynecological examination on the armchair. With this examination, the doctor will be able to confirm the pregnancy, starting from the 4-week period.

• If the fact of conception is not confirmed, then the girl will be referred to specialists of a different profile.

The second line of the pregnancy test appeared during menstruation.

There are times when a girl has already been delighted with two dashes on an express test, has begun to make grandiose plans for a baby, and then menstruation begins. Such clinical cases require mandatory medical participation. Most often, such a picture is observed with the rejection of the fetal egg, which had an anomaly or deformity of a genetic nature. Moreover, the girl herself may not be aware of such processes, thinking that just another menstruation has begun, especially if she is not obsessed with pregnancy and does not use express tests every cycle.

Although sometimes the appearance of a second cloudy strip signals the development of some kind of pathology or pregnancy complication. For example, this is likely with detachment of the fetal egg or the threat of interruption, ectopic conception, etc. All these pathological conditions are accompanied by a characteristic decrease in hCG, which is why the second line on the express test appears much weaker.

In addition, the cause of menstruation with a positive pregnancy test result may be hormonal disruptions, a one-time fertilization of two female germ cells, or a lack of progesterone hormone. Progesterone ensures the safety of the pregnant state, and if it is produced in insufficient quantities, spotting may occur. Especially often they occur on those days of the cycle, when the girl had to have her period before conception.
