Why does vaginal bleeding occur during menstruation?

Menstruation is a physiological phenomenon that occurs every month in every woman. Menstruation is the discharge of blood that occurs about a week each month. However, under normal circumstances, women will not experience vaginal bleeding during menstruation. If similar symptoms occur, everyone must pay attention to it. But why do some women experience vaginal bleeding during menstruation? Let’s take a look at it.

1. Irregular menstrual cycle, excessive menstrual flow, prolonged menstrual period or irregular bleeding. Functional uterine bleeding is abbreviated as DUB. This disease is very common in clinical practice, mainly caused by abnormal neuroendocrine function regulating reproduction. The principle of treatment is to stop bleeding quickly, adjust and establish a normal menstrual cycle after stopping bleeding, and prevent recurrence. Due to long-term bleeding, some people also have varying degrees of anemia, so correcting anemia is also very important.

2. If bleeding occurs 7 to 10 days after the menstrual period is delayed, do not assume that it is definitely late. You should pay attention to whether the amount, color, and duration of bleeding are the same as normal menstruation. If the menstrual blood is sometimes more and sometimes less, and is continuous, and is accompanied by abdominal pain, you should be careful about the possibility of ectopic pregnancy or threatened abortion; if the bleeding is more than usual, lasts longer, and there is obvious dysmenorrhea, it is more common in uterine fibroids or endometriosis. It is necessary to seek medical treatment promptly.

3. Some women may experience vaginal bleeding after having unprotected sex because they take emergency contraceptive pills. The impact of emergency contraceptive pills on menstruation is mainly manifested in changes in the menstrual cycle, which may be early or delayed. Especially for repeated users, it can cause menstrual disorders, bleeding, and continuous spotting. Therefore, it can only be used as a remedial measure and cannot replace normal contraceptive methods. It should also be noted here that some women may have their menstruation affected due to the abuse of some "health products", "breast enhancement medicines", "creams" and so on containing hormones.

4. Generally, vaginal bleeding will stop about 3 to 7 days after an abortion or miscarriage. In very few people, bleeding may be prolonged due to physical weakness, fatigue, etc., but this needs to be judged by a doctor. If there are no special circumstances and vaginal bleeding lasts longer, after excluding intraoperative injuries, cervical inflammation and the like, it is very likely that there are residual tumors in the uterus. The doctor will then decide whether to use medication or uterine curettage after examination. Otherwise, after a period of time, the residual fetal membrane tissue may turn into choriocarcinoma.

5. If a woman who has had a hydatidiform mole experiences persistent vaginal bleeding again within two years after regular treatment, it may be an early symptom of a malignant hydatidiform mole and she should see a doctor immediately.

The above is my answer to the reasons why vaginal bleeding occurs during menstruation. We have to take it seriously as it is a pathological symptom. It may be a symptom of cervical erosion, polyps or cervical cancer. At this time, we need to go to a regular hospital for examination and treatment, take medicine according to the doctor's advice, and do not delay the condition. I believe that after a period of treatment your illness will improve.
