Menstrual bloodis mainly composed of blood, old parts of uterine tissue, cells from the mucus lining of the vagina and bacteria making up the vaginal flora. Menstrual blood is different from normal blood due to its composition and its physical properties. Put another way, menstrual blood is blood mixed with secretions from the vagina and cervix, old cellular tissue, red blood cells and mucin.
The color of the menstrual blood depends on bleeding rate. Slow bleeding results in darker menstrual blood. During the first 2 days of the onset of the periods, one may see deep red color blood coming out. Whereas, the color changes to dark brown or even black near the end of the periods. This is absolutely a normal color change that happens when the blood is older and not being expelled from the body quickly.
