When will I get my first period?

Wow, im 11 and about to start! I've had the same worries! Because i ran into a girl who used to be at my school we were in kindergarten together and were the same age and she looks like shes 15! When i look i'm 12! Its just sad! So im worried too! but im a 32 A now! For the breast Development it will take up to 5 years to get the fuller shape! because your hips haven't widened it will probably happen after you start. But unlike you my hips are forming and progressing curves.For the sweat and perspiration your approcine glands are probably starting to have effect.But don't worry once you start your period you'll get your femine and womanly look.I hope i really helped! I wanna be a pediatrician.
