The clinical symptoms of miscarriage are mainly bleeding and abdominal pain. A few miscarriages do not occur with any symptoms, and the embryo is discovered to have arrested development during prenatal check-ups. As a female friend, you should understand some knowledge related to miscarriage so that you can prevent it in your life and seek medical attention in time when you find symptoms of miscarriage. The following is an introduction to common knowledge related to miscarriage. Please follow the editor to take a look.

Abortion is defined as the termination of pregnancy before 28 weeks and when the fetus weighs less than 1000g. Abortion that occurs before 12 weeks of pregnancy is called early abortion, and abortion that occurs between 12 weeks and less than 28 weeks of pregnancy is called late abortion. Abortion is divided into spontaneous abortion and artificial abortion. This section is limited to spontaneous abortion. The incidence of spontaneous abortion accounts for about 15% of all pregnancies, and most of them are early abortions.

Clinical classification of miscarriage: Most miscarriages have a certain development process, although some stages are not obvious in clinical manifestations and do not necessarily develop in order. But generally speaking, there are several processes listed below, namely clinical classification: threatened miscarriage, inevitable miscarriage, incomplete miscarriage and complete miscarriage.

Symptoms and signs of miscarriage The main symptoms of miscarriage are vaginal bleeding and abdominal pain. Vaginal bleeding occurs in those who have miscarriage within 12 weeks of pregnancy. At the beginning, the chorionic villi separate from the decidua, the blood sinuses open, and bleeding begins. When the embryo is completely separated and expelled, the bleeding stops due to uterine contraction. The whole process of early miscarriage is accompanied by vaginal bleeding; in late miscarriage, the placenta has been formed, and the miscarriage process is similar to premature delivery. The placenta is expelled after the fetus is delivered. Generally, there is not much bleeding. The characteristic is that there is often abdominal pain first, and then vaginal bleeding.

Abdominal pain during delivery is paroxysmal uterine contraction-like pain. After vaginal bleeding occurs in early miscarriage, the embryo separation and the blood clots in the uterine cavity stimulate uterine contractions, resulting in paroxysmal lower abdominal pain. The characteristic is that vaginal bleeding often occurs before abdominal pain. In late miscarriage, there are paroxysmal uterine contractions first, followed by placental detachment, so vaginal bleeding occurs after abdominal pain. During miscarriage, the size of the uterus, whether the cervix is ​​dilated, and whether the membranes are ruptured are checked, which varies according to the number of weeks of pregnancy and the process of miscarriage.

The above is a brief introduction to common knowledge about abortion. I hope it will be helpful to everyone.
