The first month of pregnancy is in the early stages of pregnancy, and the incidence of spontaneous abortion in pregnant women is relatively high, mainly manifested by vague pain in the lower abdomen and a small amount of vaginal bleeding. According to the different stages of the development of spontaneous abortion, it is divided into the following clinical types, and the symptoms tend to be different for different types: 1. Pre-eclampsia abortion: usually there will be a small amount of vaginal bleeding first, often dark red blood or bloody leucorrhea, without pregnancy discharge, and then there may be paroxysmal lower abdominal pain or low back pain. If the symptoms disappear after rest and fetal preservation treatment, and the fetus has no abnormal development, the pregnancy can be continued; if the vaginal bleeding continues to increase or the lower abdominal pain intensifies, it indicates that the abortion may develop into a refractory abortion, and the uterus should be removed in time. 2. Pregnant women should promptly carry out the uterine operation to clear the pregnancy tissues and review whether the residues are completely discharged; 3. Incomplete miscarriage: if the inevitable miscarriage continues to develop, some of the pregnancy materials will be discharged from the uterine cavity, but there are still some tissues remaining in the uterine cavity or embedded in the cervical opening, affecting the contraction of the uterus, resulting in uterine bleeding and, in serious cases, hemorrhagic shock, pregnant women should promptly go to the hospital to carry out the uterine operation; 4. The pregnancy material has been completely discharged, vaginal bleeding gradually stops and abdominal pain gradually disappears. At this time, in order to exclude the risk, ultrasound examination can be conducted at the hospital to check whether there is blood accumulation in the uterus and whether the uterus is in a normal state of recovery. Sexual intercourse should be prohibited for 1 month after miscarriage, bathing should be prohibited, and attention should be paid to strengthening nutrition and avoiding catching cold. Generally, it will basically return to its pre-pregnancy state about 1 month after miscarriage.
