Miscarriage and miscarriage refers to the termination of pregnancy at less than 28 weeks of gestation and the fetus weighing less than 1kg, divided into spontaneous abortion and artificial abortion. Spontaneous abortions are mostly early abortions, mostly due to abnormalities in the embryo itself, maternal factors or external environmental factors, resulting in vaginal bleeding and abdominal pain in pregnant women. Induced abortion is indicated for pregnancies within the third month of pregnancy, where the patient voluntarily requests to terminate the pregnancy, either by abortion or by medication.
