I Was Just Wondering If I'm Going To Grow Normally

I was just wondering if I'm going to grow normally because I'm a 15 year old girl I'm 5 foot 3, 97 pounds, and I'm a 32c, and I just got my period for the first time. I'm scared my breasts are going to grow too large because my aunt and grandma from my dad's side of the family have really large breasts. Is there an estimate of how big my breasts will be?Sorry if this is an inappropriate question or if I'm wasting your time but I was just wondering
