Calculate the exact number of days of pregnancy

After pregnancy, many expectant mothers go to the hospital for routine physical examinations. After the examination, the doctor will tell the expectant mothers how long they have been pregnant, but there is no accurate pregnancy time. So, on what day did the expectant mothers successfully become pregnant? How to calculate the exact number of days of pregnancy? Let me tell you.

How to calculate the exact number of days of pregnancy

I believe that many pregnant mothers are eager to know the most accurate pregnancy time calculation data. If accurate and reasonable data cannot be obtained, it will definitely affect the daily affairs of pregnant mothers. Many pregnant mothers hope to know when they will give birth. After knowing this data, they can adjust their work time in time and take enough rest and prepare for the birth. It is said that the first three months and the last three months of pregnancy are in the risk period, so how can some women know how long their due date is and how the number of days should be calculated. So, how do you calculate the exact time of pregnancy?

After many clinical trials, it was found that the normal delivery cycle is 280 days starting from the first day of the last menstrual period. The pregnancy period is 10 months, each year is 28 days, and pregnant women will give birth between the 38th and 42nd weeks of pregnancy. Because each pregnant woman's menstrual cycle is different, the estimated delivery date will have a deviation of one to half a month. This deviation is within the normal range.

The general calculation method is: add 9 or subtract 3 from the month of the last menstrual period, and the result is the number of months of the delivery period. Add 7 to the day level, and the result is the number of days of the delivery period. This calculation method can be used to calculate the most accurate number of days of pregnancy for pregnant women.

How long is the pregnancy?

For female friends, pregnancy is a very important thing. It means that they are creating a new life and the baby in their belly is also growing slowly. In order to ensure that the baby in the belly can grow up smoothly, some people want to know the knowledge of pregnancy time. So, how long does pregnancy last?

Normally, the pregnancy period is around 38 to 42 weeks, which is around 9 to 10 months. During the entire pregnancy period, the woman goes through the entire cycle from pregnancy to delivery, and the test tube embryo also grows step by step into a full-term fetus. During the entire pregnancy period, women must be able to protect and care for themselves well so that the fetus can grow better in the abdomen.

Every woman's menstrual cycle is of different lengths. For example, some are five days, while others are seven days. Therefore, the time of pregnancy will also be affected accordingly. Some people become pregnant in 38 weeks, while others need 42 weeks. It may even come one or two weeks earlier or later depending on the number of weeks of your menstrual cycle.
