Any information on breast growth?

Ok I'm 16 years old and can only just fit into an A bra. My mom is DD, my sister is C, one grandma is DDD, the other is C and they all started puberty at a young-looking age. Me on the other hand, I started puberty at 13 and get my period slowly too (15). What the heck is wrong with me?? I really will I had considerable breasts like the rest of my ancestral, or at least average sized...is it possible that I too will find large breasts, but of late at a slow rate? Or am I forever screwed over?

Important, female question…Help!?

All the women within my family own breasts the size of my head. I enjoy breasts the size of... well, my breasts. But I am considerably thinner than most of them. Things similar to over all body solid do play a role in how big your boobs are, so if you're differently porportioned you may freshly have smaller breasts for your undamaged life.

Puberty is a long-running process. If you're single three years in, in attendance's still plenty of time for breasts to grow.

But having smaller breasts isn't really individual forever screwed over. I mean, spend your unbroken summer in those great tanktops next to the built in bras and don't verbs about it. People are different.
