Is it normal to have 32 triple D's at 13?

I am 13 years old, and I don't know if its ok that my bra size is ok for this age. Every time I look it up there are no answers for me, as this is probably not really common. I'm around 130 pounds and I'm 5'6 (if it helps with anything?). So, I'd appreciate it if I got some answers..
