I've done it, but not really because of size. I did it because I wanted to perk up my nursing-ravaged chest. It was a good decision for me. I have seen great results on women who started out very flat. I think you'd be pleased. A lot of times when people hear "implants" they think of huge, playboy bunny breasts. This doesn't have to be the case. You walk past many women every day who have them, and you wouldn't be able to tell. Honestly, though, I'd wait until you are at least in your twenties. Some girls aren't through growing at age 19. In addition, the surgery is not without possible complications. Since it is an elective surgery, the money will come out of your pocket. If there are any complications that require revisions of any sort, you'll be responsible for those as well. Just do lots of research and be well-informed.
