The time of pregnancy for women is usually calculated based on the day after their last menstrual period, but some women's periods are irregular, sometimes coming early and sometimes late, so it is difficult to estimate the due date in this situation. So, if you can't remember the date of your last menstrual period, how do you calculate your due date?
1. If you can't remember the date of your next menstrual period in the late Qing Dynasty, you need to go to the hospital for a B-ultrasound examination to calculate the expected delivery date. Based on the size of the gestational sac during the examination, if the baby has already developed a embryo, it is more accurate to calculate the expected delivery date based on the length of the embryo. Women can consult with doctors during hospital examinations.
2. Babies are usually born around two weeks before and after the due date, and the first fetal movement occurs around 18-20 weeks of pregnancy. When women feel fetal movement, they can remember the day to calculate the due date. However, in many cases, women may not give birth within the expected due date range, and sometimes may delay or advance. Women should pay more attention to rest, walk less, and undergo regular prenatal check ups when approaching the expected due date.
3. Women can also calculate the due date based on the time of morning sickness, but each mother's physical condition is different, so it is still difficult to accurately calculate the due date. It is recommended that expectant mothers pay attention to a balanced diet and nutrition during pregnancy, avoid sexual intercourse in the first three months, and regularly undergo prenatal check ups.
