Pregnancy is calculated from that day.

For friends who have just become pregnant, they would like to know from which day the pregnancy starts. So what is the correct day to count the pregnancy from? Next, this article will introduce the correct content about the day when pregnancy starts, for your reference only. If you want to know the correct date to start your pregnancy, please continue reading! Please see the detailed introduction below.

Which day does the pregnancy start from? There are two ways to calculate pregnancy time. One is to calculate the gestational age, which is to start counting from the first day of the last menstrual period. The other is gestational age, which is calculated from the ovulation period. Because the ovulation period cannot be calculated accurately, it needs to be roughly estimated based on the last menstrual period. Therefore, it cannot be accurately calculated clinically. Therefore, the pregnancy time is generally calculated based on gestational age, which of course starts from the first day of the last menstrual period.

Since it is difficult for every pregnant woman to accurately determine the time of conception, medical regulations stipulate that the expected date of delivery is calculated from the first day of the last menstrual period. The entire pregnancy period is 280 days, or 10 gestation months (each gestation month is 28 days). Pregnant women gave birth between 38 and 42 weeks of gestation, all of which were full-term. Since the length of each woman's menstrual cycle is different, it is normal for the estimated due date to differ from the actual due date by 1-2 weeks.

What should I pay attention to after pregnancy?

Women who are pregnant for the first time will experience a series of changes both physically and psychologically. Because it is the first time, pregnant women themselves are often unaware of it. If they had no plans to have children, or do not understand their body's reactions at all, they may accidentally take medicine or neglect the details of life, which may have adverse effects on the fetus and mother.

In terms of physical reactions, there may be cold-like symptoms in the early stages of pregnancy. If you buy medicine indiscriminately, not only will it fail to achieve the therapeutic effect, you may even give birth to a deformed baby! Therefore, do not take medicine arbitrarily under any circumstances; the safest way is to see a doctor and find out the cause of the disease.

If you feel unwell, do not force yourself to do strenuous exercise or travel far at this time to avoid accidental miscarriage. In addition, if necessary, do not do X-rays at will, but check your physical condition first to determine whether you are pregnant.

The above is the correct introduction about the day to start counting pregnancy. I believe that after reading the above introduction, everyone already knows that the correct date for counting pregnancy is from that day. From the above introduction, we can understand that pregnancy time is generally calculated from the first day of the last menstrual period. I hope that the introduction in this article will be helpful to friends who want to learn more about this knowledge.
