What is a Period?

Written by Bettii

A period (also called menstruation) is part of your menstrual cycle. It happens when the body sheds the lining of the uterus, which leaves the body through the vagina as blood and tissue. Periods are a natural and healthy process, and usually occur once a month.

The menstrual cycle is controlled by hormones and typically lasts around 28 days, although it can vary from person to person. The cycle prepares the body for a possible pregnancy each month.

There are three main phases of the menstrual cycle:

Menstrual phase: This is when your period happens. The uterus lining is shed, causing bleeding that usually lasts 3–7 days.

Follicular phase: After your period, the body begins to prepare an egg. The lining of the uterus starts to build up again.

Luteal phase: After ovulation, the body gets ready for a possible pregnancy. If pregnancy doesn’t happen, hormone levels drop and the cycle starts again with a new period.

Some people may experience symptoms like cramps, low energy, or mood changes during different parts of their cycle. Everyone’s experience is different, and cycles can vary in length, flow, and symptoms.
