If vaginal bleeding occurs again about 10 days after menstruation, it is considered to be ovulatory bleeding. Because the estrogen and progesterone in the body temporarily drop during ovulation, the endometrium temporarily loses the support of estrogen and progesterone and bleeding will occur. This situation usually lasts for about 3 days and the bleeding volume is significantly less than the menstrual volume, and the bleeding will stop on its own without medication. Because after ovulation, the estrogen and progesterone in the body return to their original levels, the endometrium is well repaired and the bleeding will stop. Therefore, there is no need to be nervous when vaginal bleeding occurs again 10 days after menstruation. However, if the vaginal bleeding is more than 5 days and the amount is high, you must go to the hospital for a checkup.
