It is better to lie flat for more than half an hour after intercourse, and at the same time, you need to put your hips up, which is more conducive to pregnancy, because some women belong to the posterior position of the uterus, if you get up immediately after intercourse, the semen will easily flow out of the vagina, which is not conducive to sperm entering the uterine cavity, so it is not conducive to pregnancy. In some women with a posterior uterus, if they can lie flat for a while after intercourse and try to raise their legs as high as possible, it is more favorable for the sperm to pass through the cervix and enter the uterine cavity and fallopian tubes to reach the abdomen of the fallopian tubes to unite with the egg to form a fertilized egg. If it is not easy to get pregnant, it is recommended to have intercourse during a woman’s ovulation period, and you need to have intercourse every other day, which is more conducive to pregnancy. During the preparation period, you need to develop regular work and rest habits, ensure sufficient sleep and not to stay up late, and at the same time, you need to adhere to physical exercise every day to enhance your physical fitness, and you need to eat a balanced diet and strengthen nutrition, which is conducive to the conception of a healthy baby.
