I'm nearly 17 and my left cup is B and my right is a D. My smaller one has stayed the same since I was 13 and my right grew. It is highly noticable and very hard to hide. Ive been reading on many sites and even tho it's normal for them to be a little different, I can't take it anymore and I just want to know if my breasts will even out. I don want a false sense of hope I just want to know the chances I have of my smaller one catching up.
