[Missed Miss]

You are probably right, I will start with one of the pumps for now, baby steps I suppose would be the way to go thanks!!

No problem, hun!! (That'll be $10.00.)
Yes, you should have your hormones tested before you do ANY of this stuff, outside of MAYBE massage or Noogleberry.
I know how important it is for women to have bigger tits, and, I wouldn't want you to cheat yourself out of getting what you just might end up with in a few years. If it's any help to you to understand what I mean about how you're still growing until your early to mid 20's; when I was your age, I was 8 inches shorter than I am now! I grew another 8" over the following 3 to 5 years after I graduated high school.
Also, as I said on Lovekitten4's thread, I wouldn't count on the size of your families breasts as a judge for how big yours will be. Grandma had huge one and 3 of her 4 daughters were also huge, (at least DD's), but mom was only a B and she was in the middle of the other 3! My sisters were both flat until their late teens and are still not quite B's, and my niece was a pancake until she was in her 20's!! I THINK she MIGHT be an A by now. However, I think that just MIGHT be partially her own fault! A number of times I've seen her load up her dinner plate and, after about 10 minutes, she's done eating, and it looks like she hadn't eaten a thing!! As far as I know, if your body doesn't have any fat to put into your breasts, they won't grow very big at all!! Now, I'm not saying you should strip down to your underwear, lay out a few towels on the floor and pork out on a stack of XL pizzas with all the toppings, but, you SHOULD eat!! Guys LIKE thinner girls, but, at the same time, they also like a girl to have a little meat on her bones!! So, don't starve yourself just to get lucky with a guy! Besides, if he doesn't love you for YOU, your charm and personality and the way you are, he's PROBABLY not even worth your time!!
I REALLY hope you get to grow to the size you want to be in your bra, but, honestly, hun, it's really not that important!! A guy that REALLY loves YOU, won't care that much about how much sweater meat you have!! :-)
Take care, hun!!
