I've had my period for a year and a half, my boobs are very very small not even an a cup and i'm 16 turning 17 in one month (also year 11), when will ?

It varies: Confratulations on making the transition to womanhood. Some women are naturally small-breasted. Despite all the goofy talk, most men don't really care and will value you for who you are. There are some social advantages to appearing to have larger breasts, but looks are even more about fitness which is under your control. If you are offered implants, consider carefully. Best wishes.
