Menstruation is a natural process that occurs in the body of a woman of childbearing age. Every month, the lining of the uterus thickens to prepare for a possible pregnancy.
If the egg is not fertilized, the uterine lining sheds and is eliminated through the vagina in the form of blood and tissue.
This process is known as menstruation or menstrual period. Menstruation typically lasts from 3 to 7 days and repeats monthly in an approximate cycle of 28 days.
It is part of the female reproductive cycle and marks the beginning of a new menstrual cycle.
