The discharge of black blood during ovulation is a normal physiological phenomenon, but it may also be a symptom of a disease. This phenomenon usually occurs on days 14 to 16 of a woman's menstrual cycle, but in some people it may occur a few days earlier or later. During ovulation, a woman's ovary releases a mature egg and enters the uterus through the fallopian tube. If the egg is not fertilized, it eventually dies in the uterus and is absorbed into the body.

1. Egg discharge

During ovulation, a woman's ovary releases a mature egg. This may cause some bleeding, but it's usually mild. If you are passing a large amount of blood, you may want to consider seeking medical attention to determine if you have other health problems.

If a woman's menstrual cycle is 28 days, her ovaries will release a mature egg on the 14th to 16th day after her egg is fertilized. This may cause some bleeding, but it's usually mild. After the fertilized egg implants, blood flow usually stops.

3. Other diseases

Although the discharge of black blood during ovulation is a normal physiological phenomenon, it may also be a symptom of other diseases. If women have these symptoms, they should seek medical attention promptly. If a woman does not have these symptoms, there is no need to worry and continue to live a healthy life.
