Right now I'm at a A cup and I'm 110 lbs and 5'4. My mom is a D. I want a C cup. Will I have a C cup or B? I'm 14.

Unfortunately there's no way to tell... In a couple years you'll know almost for certain (still could grow bigger after that). Your best bet is to look at other women in your family. If your mom has a bigger size than most of your other female relatives (older sisters, aunts), you're more likely to have a B. But if she's like most women in your family, then you'll probably end up with a C or a D.
That's the closest you can get to making a guess!0
