Intercourse does not necessarily result in pregnancy, but the possibility of pregnancy exists. If you have intercourse during ovulation, the possibility of pregnancy is relatively high. If you have intercourse during the safe period, you will generally not get pregnant, and if you have intercourse during your menstrual period, it is not recommended: 1. Menstrual period: At this time, the endometrium of the woman’s uterus is shed and almost no egg cells are discharged, so the egg cannot combine with the sperm and thus cannot get pregnant. In addition, during the menstrual period should avoid intercourse, because at this time the female body resistance is weak, intercourse is easy to cause infection; 2, safe period: in the safe period intercourse, the chances of pregnancy is also relatively low. It is important to note that if ovulation is advanced or delayed due to other factors, the safe period cannot be accurately predicted; 3. The fertilization of the egg will take place in the uterine cavity, indicating successful conception. If the sperm and egg are functioning normally and the fallopian tubes are open, choosing to have intercourse during ovulation will give you a chance of pregnancy. If pregnancy is not planned in the near future, effective contraceptive measures such as wearing condoms are recommended to avoid unwanted pregnancy.
