Many people believe that intercourse during pregnancy is not allowed and will easily affect the development of the fetus, leading to the chance of miscarriage or premature birth. But if you choose the right time, it will not have a great impact on the fetus, but will have some benefits for the growth and development of the fetus. The first thing you need to do is to have the right amount of intercourse during the middle of your pregnancy, during which intercourse can promote the contraction of the uterus, which helps the blood circulation and promotes the growth of the baby. The period of blood circulation can provide more nutrition and energy to the fetus and promote the development of the fetus. In general, it is advisable not to have intercourse during early or late pregnancy to avoid the uterine contractions being too intense and leading to miscarriage or premature birth.
