Why Do We Get Cramps During Our Period?

Imagine your uterus is like a muscle that's been working really hard to get ready for a baby. When it’s time for the lining of the uterus to come out, the muscles start contracting, kind of like when you squeeze a balloon until it pops. These contractions can cause pain or cramps in your stomach and lower back. It’s like the body is saying, ‘Hey, I need a little help here!’
