When spontaneous abortion occurs in the first month of pregnancy, most patients will miscarry cleanly, but there are a few patients who may have intrauterine residue, which is generally related to the individual’s physical condition and the size of the gestational sac, and needs to be judged according to the ultrasound examination results. If after a spontaneous abortion occurs, the patient’s abdominal pain is significantly reduced, the bleeding is significantly decreased, and the ultrasound examination reveals no gestational sac tissue in the uterine cavity and no accumulation of blood, it indicates a complete abortion. The endometrium of the patient can gradually recover within one month. During this period, the patient should not have intercourse, pay attention to strengthening nutrition, supplementing protein, taking sufficient rest, not overworking and avoiding catching cold. If, after spontaneous abortion, vaginal bleeding persists and abdominal pain gradually increases, it is recommended to re-examine the vaginal ultrasound to find out whether there is residual and accumulated blood in the uterus. If residual tissue is present, it is important to decide whether medication is needed to expel the residue or to clear the uterus depending on the size of the residue. In the presence of blood accumulation in the uterine cavity, it is recommended to follow the doctor’s prescription and take oral motherwort capsules or five-plus biochemical capsules to promote the discharge of blood.
