The abortion is performed by inserting misoprostol into the vagina, and contractions will occur after about 24 hours. As the contractions progress, the opening of the uterus will slowly open up and the pregnancy products will be expelled from the vagina. In most cases, this method is used when the pregnancy is more than eight weeks old and the head-rump diameter is greater than 2 cm. When the embryo is expelled, if there is not much vaginal bleeding, it is recommended to perform a painless evacuation procedure on the second day, and it is also recommended that this method of pregnancy termination be performed under medical supervision and hospitalization.
