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 first day of menstrual bleeding is the date used for the last menstrual period (LMP). The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women, and 21 to 31 days in adults (an average of 28 days). Bleeding usually lasts around 2 to 7 days. Menstruation stops occurring after menopause, which usually occurs between 45 and 55 years of age.
