The best time for tubal evacuation is within 3-7 days after menstruation. As the endometrium is not fully repaired or there is residual menstrual blood within a short period of menstruation, performing tubal evacuation may easily lead to menstrual blood entering the abdominal cavity. Within 3-7 days after menstruation, the endometrium has been repaired and is relatively thin. The uterine operation at this time can minimize postoperative bleeding and the occurrence of endometrial pelvic implantation. A small amount of blood may flow out of the vagina with the fluid in the uterine cavity after the operation due to slight injury caused by the cervical forceps clamping the cervix during the operation. Some women may experience distension and pain in the lower abdomen, mostly due to the stimulation of low drug temperature. The pain will gradually disappear by applying hot water bags to the small abdomen. Women must choose a regular hospital for tubal ligation, prohibit sexual intercourse for 3 days before and 2 weeks after surgery, pay attention to personal hygiene, maintain a good state of mind, and participate in physical exercise to enhance their immune system.
