Period cramps can be mild or they can really hurt. But there are things you can do to feel better. Let's find out what cramps are and what to do if you get them.
What Are Period Cramps?
Cramps happen when the uterus (the place inside a woman’s body where a baby grows) squeezes. They are caused by a chemical in the body called prostaglandins (say: pross-tuh-GLAN-dinz). The squeezing of the muscles helps push the blood out through a girl's vagina during her period.
Who Gets Period Cramps?
Any girl who has her period can get cramps. Some are more likely to get them, such as girls who:
- are younger when their periods start
- have longer periods or heavier blood flow
- have female relatives who had or have period cramps
