Placenta previa scarred uterus placenta implantation induced labor at 6 months carries the risk of hemorrhage, and in severe cases requires hysterectomy and can even be life threatening. Scarred uterus is a history of a previous cesarean section or myomectomy, which greatly increases the risk of pregnancy when combined with placenta praevia and placenta implantation in a second pregnancy. When labor is induced at 6 months, the process of opening the uterine orifice is also required, so there is a risk of hemorrhage, and in severe cases the uterus needs to be removed, or even life-threatening, and a relatively safe method of inducing labor must be chosen by the doctor after a full assessment. For women with scarred uterus, it is recommended to adopt safe and effective contraceptive methods when there is no desire to have children, such as oral short-acting contraceptive pills and condoms under the guidance of a doctor, in order to avoid increasing the chances of unplanned pregnancies and increasing the risks of induced abortions and to minimize the damages to the women’s body.
