Bleeding during ovulation can have an effect on pregnancy because although there are mature follicles during ovulation, there is bleeding inside the uterine cavity and even if there is intercourse, it is not conducive to the union of sperm and egg, so it can have an effect on conception. It is also not recommended to have intercourse during ovulatory bleeding because the process of intercourse can cause an increase in bleeding and can also cause endometrial inflammation, tubal inflammation and even vaginal inflammation. Some women may also experience ovulatory bleeding and abdominal pain, including high fever. As far as possible, ovulatory bleeding should be treated first before preparing for pregnancy to avoid failure to conceive and gynecological diseases that may affect the body. Ovulatory bleeding can be treated with oral estrogen or short-acting contraceptives, and the cycle can be normalized in 2-3 months.
