at your age if you think there is something wrong hormonaly, a doctor can tell you what your body needs. I grew a little after being on birth control for a year, I think at your age if it's the right birth control it should cause some growth, but it does take time. Or you could just be very late bloomer like i was, i'm a C now but i'm almost 20, i got B's when I was about 17, and they sprouted again a year later, I also will try Noogle berry so if you decide to pump well see how it affects us both. Good luck
