A period is part of the menstrual cycle, when you bleed from your uterus through your vagina. It's a completely normal part of your body changing, and usually starts around the age of 12, although it can appear earlier or later.
Periods can be a bit of a shock when they first happen to you, but with time and understanding you'll find products which suit you to make it a much more comfortable and normal part of life.

"I hate the way they make me feel. But overall, I hate the way it is talked about.
"I hate the way I see girls asked if they’re on their period if they are in a bad mood. They could just be expressing their opinion but given the experience that they are just on their period, they aren’t being taken seriously."
Maya, Age 14
