After a miscarriage, women should rest for at least one month and wait until their menstrual period returns to be clean before having intercourse. Miscarriage, also known as miscarriage, is the termination of a pregnancy after less than 28 weeks of pregnancy and a fetus weighing less than 1kg. After miscarriage, the endometrium is damaged and it usually takes 1 month to return to normal. The hormones in the body will gradually return to normal, and you can have intercourse after your menstrual cycle is clean. After miscarriage, the cervix is loose and the cervical opening is slightly open, so bacteria can easily invade the uterine cavity. This can easily lead to vaginitis, endometritis, pelvic inflammatory disease and other diseases. After menstruation resumes and clears, the functions of female reproductive organs return to normal, so intercourse will not affect women’s health at this time. Ovulation may also occur during the period between miscarriage and menstruation, so there is a possibility of pregnancy again during intercourse. In addition, women should pay attention to rest, keep warm, wash the vulva with warm water in the morning and evening, keep the vulva clean and hygienic, and change underwear regularly after miscarriage.
