hi i'm 15 and i have a question if you could help me out thanx... how do you make ur breasts grow? mai mom has a really small chest so does that mean that when i become older i will have her sized as well? this is really giving me a hard time. now that i'm in high school, i always wear padded bras to skool. every girl at mai skool has breasts and i'm like the only one that doesn't. is it true that ur breasts will stop growing after two years you get ur period? the thing that is bugging me the most is that i'm flat chested.... help?
