What is the cause of black color at the end of menstruation?

The blood clots discharged during menstruation are bright red. If the blood clots turn black, it means that there is a problem with the body. It may be caused by gynecological inflammation, endocrine system disorders, or some organic diseases inside the body. No matter what the reason is, it is best to go to the hospital for examination and treatment in time, otherwise it will cause serious consequences.

The use of psychiatric drugs and endocrine preparations can also disrupt menstruation, causing dark menstrual blood in the late stages of menstruation.
