Miscarriage means miscarriage, which generally refers to the termination of pregnancy before 28 weeks of gestation or when the fetus weighs less than 1,000g. Most of the patients have early miscarriage. After miscarriage, doctors will try their best to preserve the pregnancy and the fetus, but if the condition is serious, termination of pregnancy will be recommended to protect the mother’s safety. Early miscarriage is defined as miscarriage that occurs before 12 weeks of pregnancy and can be caused by embryonic, maternal and environmental factors. Patients mainly present with vaginal bleeding and abdominal pain, which in severe cases can lead to hemorrhagic shock. Generally, if the condition is mild and the symptoms stop, the doctor will carry out fertility preservation treatment, such as rest and progesterone injection. If the condition continues to progress then the pregnancy should be terminated in time, otherwise it may result in the life of the mother being threatened as well. Pregnant women who have miscarriages should go to the hospital immediately for treatment, if not treated in time, the life of the mother and fetus may be jeopardized.
