Pregnant women need to be pregnant for ten months to give birth to a small life. During these ten months, the fetus will gradually develop and mature until it is finally born. But there are many pregnant women who only know their approximate number of months pregnant, but do not know the exact number of days pregnant. So, how do we calculate how many weeks of pregnancy?
The most commonly used method for pregnant women to calculate the number of days of pregnancy is to start counting from the first day of their last menstrual period. This method is very simple and accurate, and everyone will remember the date of their last menstrual period, so using this method to calculate is the simplest. For example, if the last menstrual period was on the 15th of last month, then on the 25th of this month, the pregnancy period is 10+28 days, which is 38 days.
Many pregnant women calculate the number of pregnancy cycles from the day the sperm and egg combine, that is, from the day of intercourse. However, this algorithm is actually incorrect. Because pregnancy can occur before and after the last menstrual period, and some people may even become pregnant before the last menstrual period. However, most of them only begin to conceive during the ovulation period after the last menstrual period.
In real life, many pregnant women do not know how to calculate their pregnancy days. Therefore, they can consult a doctor at the hospital, as the actual delivery time may differ from the expected time. During the first three months of pregnancy, it is important to have fewer B-ultrasound scans as this is a crucial stage of fetal development, and frequent B-ultrasound scans can affect the baby's physical health.
