For female friends who are preparing for pregnancy for the first time, there are many pregnancy knowledge that are not very clear, such as the calculation of gestational weeks. Many women, although entering pregnancy, do not know how to start counting from that day. And there will be multiple sexual encounters during the preconception period, so how do you know which pregnancy it was?
1. If a woman's menstrual cycle is very regular, the ovulation date is usually around fourteen days before the next menstrual period, and the ovulation time range is around four to five days before and after. The entire ovulation period can be around ten days, which is called the female ovulation period. The sexual intercourse closest to the ovulation date can be considered as causing the woman to conceive due to this intercourse.
2. After pregnancy, women can also go to the hospital for early prenatal check ups. By measuring the size of the gestational sac in the uterine cavity through ultrasound, the pregnancy time can also be calculated. If one's menstrual cycle is irregular, using ultrasound examination to calculate the size of the gestational sac through a formula can also determine the time of pregnancy, so it can also be used to determine which sexual intercourse the pregnancy was.
3. When a woman experiences amenorrhea and is determined to be pregnant, the number of days of pregnancy can be calculated from the last menstrual period. Every seven days is considered a gestational week, and the full forty weeks of pregnancy are considered the due date. In addition, women should pay attention to prenatal check ups in the early stages of pregnancy and promptly rule out abnormal conditions such as ectopic pregnancy to ensure that both the mother and the embryo are in a healthy state during early pregnancy.
