Within 3-7 days after menstruation, you can cooperate with the doctor for tubal lavage. Women who have uterine infections such as cervicitis, endometritis or pelvic inflammatory disease due to childbirth or miscarriage, IUI, etc., can easily cause tubal inflammation, leading to tubal adhesion or blockage. If the fallopian tube is incompetent, it will easily cause secondary infertility. In this case, you need to go to the gynecology department of the hospital in time and follow the doctor’s instruction to do tubal lavage within 3-7 days after menstruation, which is to check whether the fallopian tube is open or not, and also to treat tubal adhesion, blockage or incompetence. Rest and avoid exertion. After the lavage, women need to pay attention to rest and avoid strain. Pay attention to a balanced diet, strengthen nutrition, do not eat spicy, stimulating and cold food, and forbid sexual intercourse and tub bathing for two weeks.
