If the placenta does not detach in the first pregnancy, the same situation may not necessarily occur in the second pregnancy, but it is necessary to analyze the specific problems. Each person’s pregnancy and delivery status will be different each time. If the placenta fails to detach automatically or even implants in the first time, the second pregnancy needs to pay attention to the development of the placenta and the fetus in the labor and delivery examination. If the placenta is not expelled within 30 minutes after delivery, or if the placenta that has been delivered is incomplete and part of it remains in the uterine cavity, the placenta cannot be detached automatically. If it is due to weak contractions, promoting contractions can usually solve the problem. If the endometrium is damaged and there is inflammation caused by adhesions, etc., the placenta can not be detached automatically, and the same situation may still occur in the second pregnancy. If the placenta still can’t fall off automatically, you can take, manually peel off the placenta manually, can wait for the delivery of further treatment, don’t need to worry too much.
