You shouldn't get a boob job. Boob jobs wind up looking fake and they are painful and expensive.
You still have a couple of years for your boobs to grow. Boobs can grow until a woman is about 23.

Also, birth control can make your boobs grow bigger.

Small boobs aren't a bad thing. You can still feel womanly with small boobs. You can also try different clothing styles to make them look bigger as well.
