What it means
A period happens when the lining of the uterus leaves the body through the vagina. This is part of the menstrual cycle. Periods are a normal body process, but everyone experiences them differently.
What people may notice
Bleeding can be light or heavier, especially in the first few days. Some people also notice cramps, mood changes, tiredness, spots, bloating or changes in appetite.
Early periods can be irregular
For young people, the first few years of periods can be irregular. Cycles may not arrive at the same time each month while the body settles into a pattern.
When to ask for help
Speak to a trusted adult or healthcare professional if pain stops normal activities, bleeding feels very heavy, periods last a long time, symptoms feel frightening, or something does not feel right.
