How to know the exact period of pregnancy exactly?

After learning about pregnancy, any woman wantsto calculate its approximate time to plan a visit to a doctor, registration in a women's consultation and, of course, start preparing for a landmark event in your life - birth.

How to find out the period of pregnancy? To calculate it is not difficult, you just need to understand how to do it. It is easy to find out the duration of pregnancy, if you recall the date of the beginning of the last cycle, that is, the last time for menstruation, and count the weeks from it. Such a term is called obstetric. On the Internet, even now you can find special services that count the gestation period in accordance with the date of the beginning of the last cycle and its average duration.

But if the cycle is unstable and often changes, this method can hardly be called reliable, so a natural question arises as to how to know the exact duration of pregnancy.

It is possible to find out the term quite accurately,taking advantage of tests for a new generation of pregnancies that will especially help in the early stages, at the very beginning of pregnancy. Such tests determine the concentration of beta-hCG, a hormone that begins to develop with the onset of pregnancy, and give an approximate result.

How to find out the period of pregnancy, can also tell obstetrician-gynecologist. As a rule, doctors use two methods: a blood test for a special indicator, beta-hCG, and ultrasound.

A blood test, especially if it is made closer to10-12 weeks, can give an insufficiently accurate result, because at these times the boundaries of the norm are already too wide to establish a timeframe precisely. But ultrasound can give a better result than even the obstetric period. Measuring the size of the fetus and comparing it with the table of norms helps to establish the timing very accurately, however it is called fetal and often a little behind the obstetric. At the same time the doctor can tell how to find out the term of childbirth, to count it is not difficult.

There are several more ways to find out the timepregnancy. For example, you can learn to measure the height of the bottom of the uterus, asking the doctor to show how to do it. At first it will be difficult, but as the uterus goes up, it will be easier to make measurements. Normally, this value is equal to the week of pregnancy.

There is a way in which even doctors are oriented- the time when the future mother begins to feel how the fetus moves. Usually it occurs in 18-22 weeks of pregnancy. Some pregnant women even believe in a sign that, counting exactly 20 weeks from the moment of the first movements, you can find out the date of birth.

The closer the end of pregnancy, the easierto establish its exact term by means of ultrasound. While in the early days could interfere with the measurement error or insufficiently good equipment, now that the baby is already large, it is easier to measure it.

You can ask different doctors how to find out the duration of pregnancy, but only the woman herself can accurately give an answer to this question, focusing on her own feelings and well-being.

It should be remembered that in most cases, babiesare born not exactly in time, but sooner or later for a few days, or even for two weeks. This is considered normal, so do not worry. But it must be borne in mind that the date of birth, called by the doctor, is only an approximate date, so it is better to prepare for birth in advance.
