After a natural abortion, it is generally recommended to take a bath only after three days. Because women’s resistance decreases after miscarriage, especially the local resistance of the reproductive system, plus the outflow of blood from the vagina, which provides a good culture medium for bacteria and other pathogenic bacteria, it is easy for reproductive system infection to occur, so it is not recommended to take a bath for the first three days, and not to douche the vagina to avoid bringing external bacteria into the vagina, and also need to pay attention to avoid bathing and sitz bathing, not to have sex. All these can prevent the occurrence of reproductive system infection. After a spontaneous abortion, you should pay attention to the abdominal pain, vaginal bleeding, vaginal discharge, odor, color change, etc. to prevent the possibility of infection. It is recommended to have an ultrasound examination one month after miscarriage, mainly to understand the recovery of the uterus, and to pay attention to more rest and avoid eating cold and stimulating food.
