Women can get up and move after twenty to thirty minutes after intercourse during the preparation for pregnancy. If a woman is preparing for pregnancy, she should not get up and move immediately after intercourse, so that a large amount of semen will not flow out of the vagina, reducing the chances of conception. Women should keep lying down after intercourse during the preparation period, it is best to put pillows on the hips and other things to elevate the hips, and keep it for 20 to 30 minutes, so that more semen can enter the uterus, which is conducive to the combination of sperm and egg and thus fertilization. If both men and women have normal fertility, if women get up and move immediately after intercourse during the preparation period, although most of the semen will soon flow out of the body, but still can get pregnant, only the chances of pregnancy will be reduced.
