Your breasts will grow when your DNA says they will. Just because you have started your period doesn't mean your breasts will just pop out. Your DNA says how you will look when, and since DNA combination from your parents is completely random there is no way to predict when they will grow. I could go into detail of the chromosomes and stuff in DNA but that would take to long, but i will say that unless your parents had the DNA customarily put together (i don't think they had that tech 13 years ago though) there is no way to know. Just wait a few years, or maybe just a few month!
