Why is my second period so much worse with blood

Okay so it's super normal for your first few periods to be kind of all over the place, like totally unpredictable. Your body is still figuring things out.

Your first period might have been really light, almost like spotting, and then the next one could be heavier because your uterus is shedding more of its lining. Or maybe your hormones are just doing a little dance and trying to find their rhythm. Doctors say it can take a year or two for periods to become regular, so this totally fits into that. It doesn't mean anything is wrong, just that your body is getting used to this new period thing.

If the bleeding feels super heavy, like you're soaking through a pad or tampon every hour for a few hours, or if you're feeling dizzy, that's a good time to tell a grown-up just to be safe. But usually, a heavier second period is just part of your body's learning curve.
