Understanding Menstrual Periods: What You Need to Know

A period (also known as a menstrual period) is a regular natural change in the female reproductive system that occurs during the reproductive years. It is the monthly shedding of the lining of the uterus through the vagina. The period typically lasts for 2 to 7 days and occurs every 21 to 35 days.

During a period, the ovaries release an egg (ovulation) and the lining of the uterus (the endometrium) thickens in preparation for the implantation of a fertilized egg. If the egg is not fertilized, the levels of the hormones estrogen and progesterone decrease, causing the lining of the uterus to break down and shed. This shedding of the lining of the uterus through the vagina is what causes menstrual bleeding.

The menstrual cycle begins on the first day of menstruation and ends on the day before the next period begins. The average menstrual cycle is 28 days, but it can range from 21 to 35 days.

Menstruation is a normal process that occurs in healthy women of reproductive age. However, some women may experience symptoms before or during their period, such as abdominal cramps, bloating, mood changes, and fatigue. These symptoms are usually mild and go away after a few days.
