Vaginal bleeding that occurs 10 days after menstruation is often caused by ovulation bleeding. This is because during ovulation, the estrogen and progesterone in the body are temporarily down. When the lining of the uterus loses the support of estrogen and progesterone, a small amount of withdrawal bleeding occurs. The bleeding is much less than the amount of menstruation and does not need to be treated, but will clear up on its own after 3-5 days because after ovulation, estrogen and progesterone slowly return to their previous levels, causing the uterine lining to repair and the vaginal bleeding to stop. When ovulation bleeding occurs, it is recommended to start taking oral supplement Jiale on the 12th day of menstruation, take half a tablet once a day for 7 days.
