Intercourse is not recommended within 1 month after miscarriage. Premature intercourse after miscarriage may cause infection, leading to pelvic inflammatory disease, vaginitis, endometritis, etc., which may cause repeated lower abdominal and lumbosacral pain, and even aggravate the damage to the endometrium, leading to increased vaginal bleeding and prolonged bleeding period, and may cause secondary infertility when the endometrium is seriously damaged. After miscarriage, you need to wait until the residual tissues in the uterine cavity are completely discharged, the endometrium is completely repaired, abnormal vaginal bleeding stops, and one normal menstruation occurs, and intercourse is allowed only after the end of menstruation. If the patient’s body recovers well after delivery and basically returns to normal in about 1 month, intercourse is allowed. If the body has not recovered within 1 month, premature intercourse is not recommended. When the woman’s body has fully recovered, if there is no need to have children in the near future, it is recommended that both men and women take contraceptive measures during intercourse, and condoms can be used for contraception. If there is still a need to conceive, it is recommended that after 3-6 months after a woman has had a miscarriage, she should have regular follow-up examinations to make sure that the damage to the uterus is completely repaired and that her menstrual and ovulatory functions are normal before preparing for the next pregnancy.
