How to determine the date of birth

Each mummy with a slight excitement expects one of the most joyful and at the same time complex events in his life - childbirth. When will they come? What time it is necessary to be ready and moral, and physically, because even an ultrasound and gynecologist put different dates. Try it yourself to calculate the date of delivery with our advice.

Problems with the calculation of pregnancy arise due to the fact that, firstly, not always pregnant remembers the exact date of the last menstruation, secondly, due to the fact that the child is not a watch, will appear when the time comes. And it can come from 36 to 42 weeks. According to the method of the famous obstetrician, the approximate date of delivery is calculated in this way: on the day of the beginning of the last menstruation, it is necessary to subtract three months and add 7 days. This simple method can calculate an important event and have time to prepare. By the way, it is the neglective method that is laid in all program computing (calendars) that women's sites like boasts so much.

You can also calculate the date of delivery, you can also just know the exact date of conception. For example, you spent tests for ovulation and sure that it was all that day. Then add 266 days to the date - this will be the date of the alleged childbirth or the period for which the fruit developed normally and is ready to appear. Obsushetis are more likely to be tied to the date of the beginning of the last menstruation, since it is quite difficult to calculate exactly the day of ovulation due to the difference in the cycle. Therefore, they take into account 40 weeks, although in fact the average pregnancy itself lasts 38 weeks.

To establish up to one day the date of delivery will not be able to not be a test or doctor. It is due to the fact that every pregnancy proceeds in different ways, pathology is possible or deviations, a planned caesarean section or premature genera. However, there are a number of patterns that you can pay attention to the miracle waiting:

the longer the menstrual cycle, the longer the pregnancy lasts (if the cycle from the beginning of one menstruation before the second is more than 28 days, then it is most likely to give birth after 40 weeks);
girls usually appear slightly previously installed midwife, and boys, on the contrary, do not hurry.

And yet the most accurate are the dates that the doctor puts. The most accurate will be the ultrasound, which will make a planned inspection in the third trimester. It will be better for him to be seen the situation of the fetus, the degree of its development, as well as the position of the uterus itself and its readiness for generic activities.

Of course, each of us with trepidation freezes in anticipation of childbirth, passionately wanting to quickly hug your crumb and heroically survive that difficult process of its appearance to light. The main thing is not to panic, tune in to the positive and prepare a suitcase in advance with things for the maternity hospital, so as not to gather in all. Listen carefully a doctor - and everything will be easily and wonderful, and your baby will appear healthy and happy!
