When is the due date for pregnancy in May?

Pregnancy is a very difficult thing, but it is also a very happy thing. As a woman, from the moment you are born, you have to be a mother. Nowadays, many people talk about the issue of pregnancy time, so what is the pregnancy cycle time? How long does pregnancy last? How should the pregnancy time be calculated? If you never knew, check it out.

1. What is the pregnancy cycle time?

Pregnancy time refers to the period from pregnancy to delivery. Pregnancy refers to the presence of one or more fetuses or embryos in the body of a female mammal. 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 pregnancy. The entire pregnancy period is 280 days, or 10 months of pregnancy.

Pregnant women give birth between 38 and 42 weeks of pregnancy, all of which are 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 1-2 weeks.

2. How long does pregnancy last?

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 1-2 weeks away from the calculated 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, 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.

Calculate the expected date of delivery based on pregnancy

Add 9 or subtract 3 from the month of the expected date of delivery to get the month of delivery; add 7 to the day of delivery to get the day of delivery. For example: Ms. Chen's due date is March 13, 2008, and her due date is approximately December 20, 2008. Ms. Chen's due date is May 28, 2008, and her due date is approximately March 5, 2009. You can also calculate backwards from the first day of the due date to the 280th day, which is the due date.
