The menstrual cycle is a key process in a woman's body, preparing for the possibility of pregnancy. Here's a summarized overview:

Overview of the Menstrual Cycle

• Start of Menstrual Cycle: Usually begins between ages 12 and 15 and continues until menopause, typically around age 52.
• Cycle Length: The cycle is counted from the first day of one period to the first day of the next, varying in length among women. The average cycle lasts 28 days. A cycle is considered regular if the longest and shortest cycles vary by less than 8 days.

Cycle Phases

• Uterine Lining and Ovulation: The uterus lining thickens to prepare for potential pregnancy. Ovulation releases an egg from the ovaries, marking the most fertile period (about 5 days before and 1-2 days after ovulation).
• Menstruation: If the egg is not fertilized, the uterus lining sheds, leading to menstruation or a period, which involves the discharge of blood and mucosal tissue. This usually lasts between 2 and 7 days and occurs in the menstrual phase of the cycle.
• Period Cessation: Periods stop during pregnancy and early breastfeeding stages and permanently cease at menopause.
