Hi I am 15 years old too. I have not started my period ever!!!! I have discharge and a little bit of boobs but not much. Everyone at school makes fun of me bc I have no boobs but they don't know I haven't started my period yet. It's to embarrassing to tell. Only my friends and family know. I just wish I would grow into my body I have long legs and a short torso I look like I'm twelve.
