​Menstruation is a monthly biological process experienced by most females of reproductive age. It involves the shedding of the uterine lining, leading to vaginal bleeding, typically lasting about 3 to 7 days. Hormonal changes, primarily estrogen and progesterone, regulate this cycle, which usually occurs every 28 days but can vary. Menstruation is essential for reproductive health and fertility, indicating a woman's ability to conceive. Proper menstrual hygiene is crucial, and efforts are ongoing to educate and eradicate social stigmas associated with menstruation globally.
