How to calculate the due date if you haven't had your period

When a woman is pregnant for the first time, she may feel panic and not know what to do for a period of time during pregnancy. There are many things that women cannot do after pregnancy. They should pay attention to rest to maintain the normal of various indicators of the body. Many women are curious about the due date. How is this due date calculated? Then, let me tell you how to calculate your due date based on the due date of pregnancy!

Generally, after the pregnancy is confirmed, the pregnant woman will be informed of a due date, and this due date is calculated based on the first day of the woman's last menarche. It is approximately 266 days from artificial insemination to delivery of the pregnant woman, and the woman's pregnancy is completed 2 weeks after the menarche. Therefore, the woman's gestational age is 280 days from the first day of the last menstruation. However, due to individual physical reasons, the due date may be different, and the time calculated by the doctor is only an approximate data. Generally speaking, it is normal for pregnant women to give birth within 2 weeks before and after the due date.

However, if some pregnant women cannot remember their due date, they can use the above two methods to calculate:

1. You can roughly estimate it based on the time of fetal movement. Fetal movement usually occurs within 18-20 weeks of pregnancy. Add 20 weeks to this time to calculate the approximate date of delivery.

2. In a family with the necessary conditions, ultrasound can be used to measure some diameters of the fetus' body for calculation. In addition, the gestational age can be measured and the due date of the pregnant woman can be calculated.

Generally speaking, calculating the due date based on the most fertile due date cycle is a more effective method. Therefore, mothers who are preparing for pregnancy must remember their most fertile due date. It is also common for women to have irregular menstruation and unstable delivery dates. Therefore, during the pregnancy preparation period, you must pay attention to your diet regularity. Do not stay up late during the pregnancy preparation period. Developing good habits is also beneficial to the growth and development of the baby.
