How to calculate pregnancy time
In order to calculate the duration of pregnancy, we need to know the time of conception. The time of conception usually refers to the first day of a woman\’s last menstrual period. If your periods are regular, you can calculate your pregnancy period by counting your cycles to predict when you\’ll be pregnant. Generally, the pregnancy period is calculated based on the number of weeks after conception, with a week being 7 days. For example, 40 weeks pregnant means you have been pregnant for 280 days.
In reality, the timing of pregnancy can be a little more complicated than the menstrual cycle. If your menstruation is irregular, or you choose artificial insemination after failure to conceive in the natural cycle, you need to use B-ultrasound, progesterone testing, early pregnancy reaction and other indicators to determine the time of pregnancy. In addition, if the child is born early or needs to be induced early, the duration of the pregnancy will also need to be adjusted accordingly.
How to calculate pregnancy period
The calculation method of pregnancy period is based on international practice, dividing the time after conception into three months, namely the early pregnancy period, the second trimester and the third trimester. During the first trimester, the embryo is establishing a healthy reproductive system and begins to form organs such as the head, mouth, face, eyes, ears, and limbs. In the second trimester, the fetus develops rapidly, and the lungs, heart, liver, stomach and other organs are basically developed and begin to function. In the third trimester, the fetus begins to store fat and gain weight in preparation for birth.
Generally speaking, you should maintain a good nutritional status during pregnancy and appropriately increase the intake of nutrients such as protein, calcium, and iron. At the same time, it is necessary to conduct standardized prenatal examinations, monitor the physical conditions of pregnant women and fetuses, and adjust and control the labor process at any time.
