Regardless of whether a pregnant woman had a vertical or horizontal incision during her previous cesarean section, it is generally not recommended that a pregnant woman who has had a cesarean section should have a normal delivery when she goes into labor again. After a C-section, the uterus will easily form a scarred uterus, and the connective tissue at the incision lacks elasticity, which makes it difficult to produce regular contractions. If a woman undergoes a normal delivery after a second pregnancy, the abdominal pressure will easily cause uterine rupture or hemorrhage, and in severe cases, the baby may be suffocated in the uterus. Therefore, women who have a cesarean section are generally not recommended to have a normal delivery. If the pregnant woman recovers well, there are no high risk factors for a normal delivery, and the woman’s willingness to have a trial of labor is particularly high, and the local medical conditions are particularly good, a cautious trial of labor may be considered, and in case of an accident, it should be converted to a surgical delivery in a timely manner.
