Question.

I know this is a random question, but I don't know if I should be concerned or not. Anyways, back In August 2013 I had my first baby boy. I started out as a size 32A and got to a C cup. Well, here I am at 14 weeks pregnant and I'm still a 32A. Is this normal at all to still be the same size. In the beginning my boobs did hurt quite a lot, but no growing. Should I be concerned about this? If it helps any I'm 24 years old, I'll be 25 by time this baby is born.
