The normal bleeding during ovulation is a physiological phenomenon and is not necessarily related to pregnancy. If the patient has sexual intercourse, there is a certain chance of pregnancy, but the chance is very small. Ovulatory bleeding is related to the patient’s own hormones. It is usually caused by the disruption of estrogen secretion, which causes the endometrium to shed and leads to vaginal bleeding. Ovulatory bleeding can also be caused by gynecological inflammation, which can have a certain impact on a woman’s pregnancy. During normal sexual intercourse, if the endometrium returns to normal, the chances of pregnancy also exist. The sperm and egg meet to form a fertilized egg, which can grow and develop normally after pregnancy will have a history of menopause and early pregnancy reactions, like nausea and vomiting, which can be combined with these symptoms to initially determine if there is pregnancy, and then perform blood HCG and other tests to confirm the diagnosis. Patients with ovulatory bleeding should promptly observe the amount of bleeding and other abnormal body symptoms, and go to the hospital gynecology department for hysteroscopy and cervical CT examination if abnormalities occur.
