Question: "Pregnancy" is starting to count after the menstruation, still there is still a menstruation?

I believe many of pregnant or just pregnant mothers are very confused. When I went to the hospital for the first time, when I was pregnant, the doctor asked the first sentence is when the last menstrual period is? Is "pregnancy" began to count after the menstruation, still did not come to menstruation?

First of all, we must know that medical regulations, the number of pregnant days is to calculate from the last menstruation of pregnant women. Maybe expensive mothers don't understand the first day of this last menstruation, which day, here, I will give an example, Lily last month's "big aunt" is reported on October 1, 2018. The menstrual period is 7 days, and checks Li Li is pregnant, then Lily is now pregnant with the number of days of pregnancy is starting from October 1. Some expectant mothers are doubtful, and I am still coming to menstruation, how can I get pregnant? In fact, this day is just an estimated date. In general, 14 days after menstruation is ovulation, but because the irregular menstrual cycle, the days of ovulation is not fixed, and the date of menstruation can be recorded, so The day of the menstrual period was used as the initial date of pregnancy. So in the days of menstruation, it is relatively accurate.

Second, we know that the calculation of pregnancy is calculated from the first day of the last menstrual period, plus the number of months of this date to nine or minus three, and it is the month number of the expected date of delivery. Then add this date of this date to seven days, the number of days in the expected date of delivery. There is still a lot of pregnant mommy to remember your menstrual cycle, then there is no relationship. If you remember your first fetal movement. Since the initial maternity usually occurs the first fetal movement around 20 weeks, then the 20 weeks will be pushed, and it is your expected date of birth. The calculation rule of the proliferation is calculated at 0 points with the time point of the last menstrual period. In fact, pregnancy around the last menstrual period, 0 to 2 weeks in pregnancy, has not happened at all times. At 0 weeks of pregnancy, the eggs that combine with sperm have begun to activate and develop. At 2 weeks of pregnancy, this egg will become a superior follicle, and the sperm is combined to form a fertilized egg, and this is the premium The beginning, that is, the pregnant age is 2 weeks = giving age 0 week. Two weeks before gestational age are not pregnant, or it is understood that pregnant age is actually calculated from the development of eggs.
