There is also a chance that your black period blood is caused by an infection or STD. Uterus infections can cause blackening as well as many STDs. Women that have sex during their cycle also experience black bleeding because the blood was pushed back into the vagina and can become trapped as a result.
Explaining the Underlying Causes. Having brown period blood is COMPLETELY normal. It is called âold bloodâ and comes out either at the start or end of a womanâs period. In the middle of menstruation, this is heavier and takes a pink or red color. Blood becomes brown because of its iron content â iron turns brown when it is exposed to air.
