Im 27 and im an A cup your lucky most likely they will grow. That age i was flat.
First comment said it perfectly. When I was your age, my Boobs were just going into the b's. They continued to grow even after I graduated high school. I'm now in the DDs or Es and still growing. I'm 25.. I wish I had smaller boobs. Clothes look better ( not to mention I have to buy large or xl so they fit on the boobs. Too loose everywhere else), i cant shop at all bra stores, jewelry looks better especially long necklaces, all the cute bras are in smaller sizes, I look much heavier because of my Boobs, I have back problem, it's hard to be comfortable when trying to sleep, etc. I can go on and on. If you really like the appearance of bigger boobs, buy a padded bra. That's what my friends and I used to do.
The first comment it's right. Even if you don't realize it now, guys do pay attention to you brain more than your boobs. And the grass is always greener... I'm a 34E and is gladly trade you. Mine didn't stop growing until I was 22, and at your age I was a 32C. And what size you want then to be doesn't matter. It's not like you're going to be able to stop then from growing when they get where you want them to be. You're too young to be worried about that.
Hi there. Well, it is hard to say. Breast size is dependent on genetics, hormones and fat. When did you go through puberty, get your first period? Breasts change throughout life-- pregnancy, aging, etc. Gain weight, your breasts will grown. Lose weight, they'll shrink. Get pregnant, they will grow. Nurse a baby, they will grow. When finished, they will shrink.
I would try not to get caught up in something like breast size. Who is that for? Guys? You'll impress a lot more men in your lifetime with your brain than your breasts. So, work on what you can control--- school, activities, being an interesting, well rounded person. :>) good luck
