Black leucorrhea during ovulation is a common symptom that usually occurs between the 14th and 19th days of a woman’s menstrual cycle. For many people, this symptom may not be of much interest because not every woman experiences it. However, for some women, this symptom can have a significant impact on their health.

Black discharge can occur for a variety of reasons. One common cause is vaginal flora imbalance. When a woman's vaginal flora is out of balance, some abnormal bacteria may be produced, which can cause vaginal inflammation, leading to the appearance of "black discharge." Another common cause is vaginal bleeding. When a woman's vaginal bleeding stops, dark discharge may reappear.

In addition to physiological reasons, the appearance of "black discharge" may also be caused by other factors, such as psychological stress, malnutrition, drug side effects, etc.

Although "black discharge" is not a symptom that every woman will experience, it can have a significant impact on their health. If women frequently experience this symptom, they should seek medical attention promptly so that the underlying disease can be diagnosed and treated. In addition, women should pay attention to maintaining the balance of vaginal flora and avoid excessive use of antibiotics and other drugs to avoid imbalance of vaginal flora.
