Pregnancy Weeks Calculator

How to calculate the number of weeks of pregnancy? What is the method of calculating gestational age? Because every pregnant woman cannot accurately tell the time of pregnancy, therefore, medicine requires that the expected date of delivery be calculated from the first day of the expected date of pregnancy. The total pregnancy period is 280 days, 10 gestational months (each gestational month is 28 days, or 40 weeks). However, many patients do not understand the method of calculating gestational age, and have more or less doubts about what it is. Let’s take a look at it together below.

Women give birth around 40 weeks of pregnancy. The due date in the medical sense does not mean that a woman will give birth at 40 weeks of pregnancy. It may be a week earlier or a week later. Of course, every woman's health condition is different, so the time of delivery will also vary. According to the scientific calculation method, the actual time of delivery of women can be calculated. Of course, women should do a good job of medical care during pregnancy. After 37 weeks, the baby is full-term, and the baby may be born at any time, so be fully prepared. It is necessary to prepare some daily necessities needed for pregnant women to give birth.

The normal menstrual cycle is 28 to 30 days, and the menstruation usually ends in 3 to 7 days. When the menstrual cycle is regular, the gestational age is calculated based on the first day of the expected delivery date. If your menstrual cycle is irregular, the gestational age can be calculated based on the first B-ultrasound results. The total gestational age is 40 weeks. It is recommended that you eat more fresh vegetables and fruits during pregnancy, and eat more lean meat and eggs to supplement protein and enhance immunity.

How to calculate gestational age?

In medicine, the gestational cycle is 7 days a week, 4 weeks a month, a total of 40 weeks is 280 days, only 9 months plus 10 days.

How to determine the time of pregnancy?

The cycle of pregnancy, at each stage of pregnancy, the requirements of each stage have different developments, and the due date of the fetus can be calculated. There are many different calculation methods, such as body temperature method, uterine height measurement method, etc., but the following two methods are widely used, especially the second one.

First, calculate from the time of the last menstrual period. This is a pregnant woman with a relatively regular menstrual cycle. Add nine days to the month of her last menstrual period to get the month of her due date, and add seven days directly to get the day of her due date. This method of operation is very simple to produce. Although it is not very accurate, it has certain practical value.

Second, use the B-ultrasound examination results for calculation. It is a relatively accurate optimization algorithm, which is more accurate than calculating according to the due date of pregnancy. It can also roughly estimate the length of the fetus, such as the biparietal diameter of the fetus, the fetal femur length, etc., to calculate the pregnancy time and determine the actual delivery time. This method is very common and relatively accurate. In my case, my due date and due date were delayed by one week, which means I became pregnant relatively late. My water broke on the night of my due date, so the due date was still very accurate.
