You will develop over time, and they will grow. Does your mother have bigger breasts?

You should look at your family members to figure out the genetics, and deduce what you want by that..

Also, getting pregnant makes them bigger for a while.

You are still young, relax. Breast tissue is mostly fat, when you gain weight you usually gain some in your breasts. You will grow more.

nancy u is right, as you grow and your body shape changes and you get body fat in different areas your breasts will grow on their own. And enjoy your small breasts while you have them, you can do more athletics and jump around more comfortably if they are smaller

Oh shut up. Boobs only make guys horn dogs. You don't want boobs. Jk, I hated when older people told me that. sorry. lmao butt if I were you, I would just get buy a padded bra so it looks like you have a little something. (: & i really don't have any advice on making your boobs actually bigger. You'll get what you get when you get it, sweetie. Really, don't worry. One day they'll just suddenly get bigger. trust meeeee

Every female is different, but usually it depends on your genetics. I didn't start until I was 14 1/2 And If by chance you are a small cup size .By any means PLEASE don't go for plastic surgery.
