Ovulation bleeding refers to vaginal bleeding that is heavy and dark in color during a woman's menstrual cycle. It usually occurs around the 14th day of the menstrual cycle. Ovulation bleeding is usually caused by the shedding of the endometrium, causing breakthrough bleeding, and will not have a serious impact on a woman's menstrual cycle and fertility. However, if a woman experiences delayed menstruation during ovulation bleeding, this may have an impact on a woman's fertility.

Ovulatory bleeding itself does not cause a delayed period, but if a woman experiences a delayed period during her ovulatory bleeding period, it may be due to other factors. For example, women may suffer from other diseases or symptoms, such as endocrine disorders, endometrial diseases, posterior uterine position, etc., which may cause delayed menstruation. In addition, women's excessive use of drugs in daily life, such as oral contraceptives, hormonal drugs, etc., may also lead to delayed menstruation.

If a woman experiences delayed menstruation, she should seek medical attention promptly to find out whether there are other factors. In addition, women should maintain good living and dietary habits and avoid excessive use of medications to reduce the risk of delayed menstruation.
