A third cesarean delivery can be considered at 38-39 weeks of gestation and the appropriate preparations should be made before the operation. It is also recommended to be prepared with blood preparation to avoid the possibility of giving blood transfusions for resuscitation due to heavy bleeding during the operation. The main problem is whether the uterine scar can withstand a third pregnancy. It is generally recommended to consider another pregnancy at least two years after the second cesarean section, when the ultrasound indicates that the uterine scar is healing well. What are the risks during pregnancy? First of all, the aura uterine rupture, especially in late pregnancy when the uterus is more sensitive and prone to pseudo contractions, the more frequent the contractions, the thinner the lower segment of the uterus will be, the pregnant woman may feel pain at the lower segment of the uterine scar, no matter how many weeks of pregnancy should be promptly hospitalized and the physician will determine whether to terminate the pregnancy. Secondly, we should pay attention to review the ultrasound during pregnancy to rule out the combination of low placenta and placenta praevia, especially in the case of fatal placenta praevia, which is a low placenta position covering the uterine scar and prone to placental implantation, which is more risky and requires an earlier gestational week for termination of pregnancy. If the pregnancy is all going well, the pregnancy can be maintained until 38-39 weeks for termination, with special cases that need to be dealt with at any time.
