How is the onset of pregnancy?

What changes occur in the female body at the very beginning of pregnancy and which symptoms are the first signs of the news of such a delicate situation. Why exactly the beginning of pregnancy is so important for the further development of the fetus? This is in our article.

After 12 hours after fertilization, the oocyte starts dividing into two cells joined by a septum, but then this septum disappears and a morula forms. So the doctors called the cell, which in the future will become an embryo. The next week, the embryo divides and grows, and its progress to the uterus is the final destination. This is how the beginning of pregnancy looks like, which the future mother does not even guess.

Somewhere on the 7-8th day the fetal egg, already in the uterine cavity, begins the process of fixation in it. It is from this moment on that a woman can already feel some changes taking place in her body.

After the embryo is attached to the female body, hormonal restructuring begins. The life activity of the fetus is completely carried out at the expense of the female body, since a single circle of blood circulation for the mother and child appears. Such a start of pregnancy Already well feels and understands the woman herself, it can be confirmed by a test or gynecologist.

Symptoms of an interesting situation

How to find out about the coming pregnancy before the emergence of critical days?

The answer to this question is simple for those who maintain a constant schedule for measuring basal temperature. During the pregnancy, the temperature decreases, usually for one day.

For everyone else - even an ultrasensitive test will show the onset of pregnancy only from the first day of the delay. And with the help of ultrasound, pregnancy can be determined only in the third week. But some characteristic symptoms of pregnancy 1 month still has. And this:

• Increased sensitivity of the breast, in particular, the nipples;

• Can be observed a drastic change, and without any apparent cause, temperature or pressure;

• Nausea, vomiting and headache, which may appear from the second week of pregnancy;

• Heartburn or bloating;

• Increased intolerance to various odors;

• Aversion to certain foods and a special love for others.

Quite often, the onset of pregnancy symptoms of malaise and increased fatigue, which, as a rule, appear because of hormonal adjustment and the adaptation of the organism to a new role, will mark the beginning of pregnancy.

Threat of miscarriage in the first weeks

The first month is very important for the coming pregnancy for several reasons:

• Can continue to take hormonal contraceptives, which will certainly provoke spontaneous abortion;

• The use of alcohol or nicotine also acts unfavorably on the fetus;

• Strong medications can lead to genetic abnormalities of the fetus and cause the development of certain intrauterine anomalies.

But at the stage of "beginning of pregnancy" the fetus lives on the principle of "all or nothing", i.e. If in the first few weeks the fetus managed to survive under the influence of some unfavorable factors, then, most likely, further normal development of the fetus will occur. If not, that is. There is a spontaneous abortion, then, most likely, a woman will not even feel anything, because the size of the fetus is still too small. The only manifestation will be a little overdue menstruation.
