If you have intercourse after pregnancy, you will not get pregnant again because you must have sperm and eggs to get pregnant. At this time, although there is sperm, there are no mature eggs. After pregnancy, due to the increase of estrogen and progesterone level, it will inhibit the hypothalamus and pituitary gland to secrete gonadotropin, so the follicles will not grow and will not appear to be mature, so it is impossible to get pregnant again with intercourse. You cannot have intercourse in the early stages of pregnancy, as this time is unstable and can easily lead to preterm abortion or embryonic arrest. During the 3-7 months of pregnancy, you can have intercourse, but you must be careful when having intercourse, and you must be gentle and not too frequent. After the seventh month of pregnancy, because the pregnant woman’s abdomen is larger, the fetus is also larger, if intercourse may cause premature rupture of the fetal membranes, causing premature birth.
