Mine is doing the same thing right now, Its not cramps though it just hurts
I am twelve and I have the same question mine hurts on the left side at the bottom I don't know its scary
Maybe you have drunk to much things or eaten but right now the BOTTOM of mine is hurting so bad and I would have 2 ask the question as well ouch oo it hurts
It's problably your period.... Don't worry
It could be a number of things I suppose. Depending on the area, it could be cramps.
It could be you have something living inside you
Lol @ person on top of me. 3 years ago I had the same thing at the same age. I think you should pick up so pads or tampons just to be safe.
