A history of abortion is not necessarily related to the possibility of a normal delivery. If the number of abortions is too high, it will cause adhesions in the uterine cavity, which will affect the chances of conception. If a secondary infection of the reproductive tract occurs after an abortion and is not treated in time, it can travel up to the cervix and cause inflammation of the reproductive tract. If pregnancy without standardized treatment, the delivery period will be affected, such as causing intrauterine infection or postpartum infection. Therefore, if acute vaginal inflammation is detected during pregnancy, it should be treated aggressively. Miscarriage increases the incidence of placental implantation, placental adhesions, and cervical insufficiency. Cervical insufficiency during pregnancy may lead to complications such as miscarriage or preterm labor. If uterine perforation or severe cervical injury occurs during an abortion, it is dangerous to choose vaginal delivery at this time because of uterine perforation and the possibility of uterine rupture during the episode. In the case of cervical injury, severe cervical laceration may occur during labor. Cesarean section is generally recommended and is relatively safe. The possibility of a normal delivery depends mainly on the size of the fetus, the condition of the pelvis, as well as the strength of the labor and psychological factors of the pregnant woman. If there are no abnormalities, vaginal delivery is the preferred option in most cases.
