Hi Lola!
I love your username as well
I'm 21 and your height, so nice to see somebody similar on the boards!!!
You can see my starting pics and experiences in my own topic. I started out a bit bigger at a fuller 32B, and I am not a diligent noogler at all, but I believe I've seen nice results so far especially comparing to this.
The most helpful thing for me at least since I have a narrow ribcage is to noogle 1 cup at a time. This way I feel that I can manipulate the domes better somehow, like pressing down the cups on the ribcage in the opposite direction of where I would want growth( for example, if you would like to improve your tops, press on the bottom of the cups near your ribs, if you would like bottom increase, then press on the upper rims, etc). For cleavage building, many girls just simply try to position the cups as far up as they go below the collarbone and pump from there. Since starting in Nov 2010, I've mainly been using the pump and release method, however recently I started switching to pump and hold. This seems to get me better results, without increasing the size of the nipples/areola. Even with pump and release, they go down after the swelling subsides, but I would rather not risk it
Regarding permanent indentations, I think this usually happens in case you are using too much pressure and/or are overpumping. If you pump just until you feel a slight pull, you shouldn't have any issues.
I agree with PetiteNShy, you have a nice shape and a good starting point, so I think you will do well and even if you might not get B's by Christmas(although it can certainly happen), you should definitely get fuller A's!
Happy pumping and good luck, will be looking forward to your progress
