What is a menstrual period?

Alright, kiddo, imagine your body has a tiny, cozy little nest inside called a uterus. This nest is where a baby could grow if someone wants to have a baby. Every month, the nest gets ready just in case a baby wants to start growing there. It gets all soft and comfy, like a pillow fort!

But most of the time, no baby is ready to grow, so the body says, "Okay, let's clean up and start fresh next month!" So, the nest's soft stuff leaves the body, and that's called a menstrual period. It's like the body's way of tidying up and getting ready for the next month. Grown-ups use special pads or tampons to catch the stuff so it doesn't make a mess. It's all a normal and healthy part of growing up!
