It is not recommended to start preparing for pregnancy one and a half years after a cesarean section. It is generally required that you get pregnant two years after a cesarean section. The uterine wall is scarred after a cesarean section and it takes time for the scar to recover, so it is not recommended to get pregnant a year and a half after a cesarean section if it has not been repaired. If the recovery time is not enough, the pregnancy will soon be repeated. As the uterus enlarges during pregnancy, the uterine wall becomes thinner, and the scar connective tissue at the incision that has not recovered well lacks elasticity, especially at the end of pregnancy or during delivery, it is easy for the uterus to rupture, resulting in hemorrhage and hemorrhagic shock, which threatens the life of the pregnant woman and the fetus. Therefore, one and a half years after the cesarean section is not recommended to start preparing for pregnancy, it is recommended that women make adequate preparations for pregnancy before conception, and then prepare for pregnancy when the conditions are suitable, and if necessary, need to consult a doctor in time, under the guidance of the doctor to prepare for pregnancy.
