If you bleed again after 7 days of menstruation, you need to exclude bleeding caused by organic lesions first, and you also need to exclude bleeding caused by pregnancy. If the above two conditions are excluded, ovulatory bleeding is mostly considered. Ovulation in women usually occurs about 14 days before the next menstrual period, that is, about 7 days after the menstrual period. During this period, the estrogen level of women fluctuates dramatically. The estrogen level of women before ovulation can reach 200 pg/ml, and will drop after ovulation, in which case the endometrium may be irregularly shed because it cannot be continuously maintained by estrogen. In this case, the endometrium may be irregularly shed because it cannot be sustained by estrogen. No special treatment is needed for this condition, but the patient should pay attention to the cleanliness of the vulva, maintain good living habits and not stay up late.
