Im a 12 year old girl and ive gone threw almost all the stages of puberty(Breast development,pubic hair,discharge,underarm hair,and my period.) The only thing that i haven't had happen is gaining weight.Im getting taller but i thought that when you get taller you fill out like you get hips and stuff.Im very bonny and its not because i don't eat because i eat very much.But everyone keeps telling me when i get in high school ill gain weight but in all these books ive read it said when your 13 you go through a weight spurt but if you haven't after your 15 you should see a doctor.So can you please just tell me whats going on with me??Or how i can gain some weight?
