Why do women get their period monthly?

Women typically get their period monthly as part of the menstrual cycle, which prepares the body for a potential pregnancy. Each month, hormones regulate the thickening of the uterine lining in anticipation of a fertilized egg. If fertilization doesn’t occur, the body sheds this lining, resulting in menstruation. This cyclical process is driven by hormonal changes and typically lasts about 28 days, although it can vary among individuals.
