If you experience bleeding after intercourse during pregnancy, but there is no pain in your stomach, you need to try to take care of bed rest and observe the size of the bleeding. In general, if the action is too violent or rough, it can easily cause the vaginal mucosa to rupture and bleeding can occur. However, the more common reason is that when the placenta is too low in the middle and late stages of pregnancy, or when the placenta is anterior, intercourse can easily lead to abruption of the placenta and bleeding will easily occur, but there will be no stomach pain. This situation can occur repeatedly, and if the bleeding is relatively large, it can easily lead to hemorrhagic shock, and in serious cases, it can easily lead to intrauterine growth arrest and fetal death, which should be noted.
