How many weeks of pregnancy

Pregnancy lasts for ten months, in other words, the pregnancy period is ten months. However, based on the calculation of the due date and the specific delivery period, some people give birth before ten months of pregnancy, while some may give birth after ten months of pregnancy. So how many weeks is the pregnancy in the end? Let’s take a closer look at this issue.

How many weeks is the pregnancy?

Pregnancy time refers to the period from pregnancy to delivery. Pregnancy (or pregnancy, pregnancy) refers to the fact that a female mammal (including humans) has one or more fetuses or embryos in her body. Human pregnancy is the best scientifically studied of all mammals.

Because every pregnant woman cannot accurately tell the time of pregnancy, medicine requires that the expected date of delivery be calculated from the first day of the pregnancy. The entire pregnancy period is 280 days, 10 gestational months (each gestational month is 28 days).

Pregnant women give birth between 38 and 42 weeks of pregnancy, which is considered full-term. Because each woman's menstrual cycle is of different length, it is normal for the estimated due date to differ from the actual due date by 1 to 2 weeks.

The calculation method is to start from the first day of the expected delivery date of pregnancy, subtract 3 or add 9 to the month, and add 7 to the day. For example, if the first day of the pregnancy is April 21, 2000 in the Gregorian calendar, the due date should be January 28, 2001. If you only remember the first day of the lunar calendar due date, you should calculate it into the solar calendar and then calculate the due date. It must be emphasized that the actual delivery time of a pregnant woman may be 1 to 2 weeks away from the estimated delivery date. If you can't remember the due date of your pregnancy, you can ask your doctor to estimate it based on the time when the early pregnancy reaction starts to appear, the time when the baby's fetal movement starts, the height of the uterine fundus measured by hand, and the length of the uterus measured with a ruler.

Common problems for pregnant women: Common problems in early pregnancy

1. Diet

In the early stages of pregnancy, the diet of pregnant women may change, also known as mouth ulcer. At this time, you should eat some light-tasting, easy-to-digest foods. Eat more vitamin-rich vegetables and fruits and less greasy food. Remember to drink water or milk when you wake up every morning. In the diet, you should also pay attention to eating small meals frequently, and don't be too full at each meal.

2. Therapeutic drug level

You must pay attention to taking medicine in the early stages of pregnancy, because this stage is the most important stage for the growth and development of every organ in the fetus. If mothers blindly take medicine because of illness, and take medicine that pregnant women cannot take, it will affect the growth and development of the fetus and easily cause deformities. Therefore, if mothers get sick and need to take medicine in the early stages of pregnancy, they must take medicine that is beneficial to the fetus under the guidance of a doctor.

3. Natural environment during pregnancy

Due to the necessities of early pregnancy, in addition to taking medicine and paying attention to thinking, living environment is also very important. In addition to the mother herself not smoking and drinking, it is best to eliminate the smoking environment. To prevent the thick smoke from causing insufficient oxygen to the fetus. Mothers also do not need to go to public places with poor sanitation or factories that discharge harmful substances to avoid fetal deformities caused by harmful substances and viral infections.
