How Common Is Miscarriage After Seeing a Heartbeat?

The main symptoms of abortion are vaginal bleeding and abdominal pain. Vaginal bleeding occurs in those who have a miscarriage within 12 weeks of gestation. At the beginning, the villi are separated from the decidua, and the blood sinus is opened, and bleeding begins. When the embryo is completely separated and discharged, bleeding stops due to uterine contraction. The entire process of early abortion is accompanied by vaginal bleeding; in the case of late abortion, the placenta is formed, and the process of abortion is similar to premature delivery. The placenta is discharged after the fetus is delivered. Generally, there is not much bleeding. Abdominal pain is a kind of paroxysmal pain during abortion. After vaginal bleeding occurs in early abortion, embryo separation and blood clots in the uterine cavity stimulate uterine contraction, and paroxysmal lower abdominal pain occurs, which is characterized by vaginal bleeding that often precedes abdominal pain. Late abortion has paroxysmal uterine contractions and then the placenta is stripped, so vaginal bleeding occurs after abdominal pain. The size of the uterus, whether the cervix is dilated, and whether the membrane is ruptured during miscarriage vary depending on the number of weeks of pregnancy and the process of abortion.
