First period question for girls only?

I still don't get what your question is: Your period? Or your weight? I'll answer both to make it easier for you. Your period: Dude, you're still young. You're barely 13,(actually you're not even 13 yet) meaning your 12, and you expect to get your period at that time? Look, I didn't get my period until I was 14, so don't get your hopes up. Your weight: You're very, very normal.
