A member asked:

What does black menstrual blood indicate? i am in the second day of menstruation and it has been dark from the start. today, it is completely black.

A doctor has provided 1 answer

Old blood: As the blood deteriorates it changes colors from bright red to burgundy to brown to yellow and sometimes to black. Black blood means that it has been sitting in a "closed" location for some time.
