Have my breasts stop growing? I'll say it's way smaller than a 32A. I'm only 15, the last time my breast grew was when I was 13. Since I don't know my breast size or bra size to wear I wear a S sports bras and that is too big for me

At 15? No, they most likely have not stopped growing. However if you are very athletic, there is a chance. Breasts are primarily mad of fat tissue and if you have low body fat you will have a small chest.
