swelling after a mammoplasty

I had an mammoplasty Dec 18th, I know there is a lot of swelling but I was wondering if my breasts will get smaller after it goes away. I started really big and since I have had many issues and since I'm a runner I wanted to go small. Dr said a c cup and I told him okay but if he can go smaller (with no problems) I wouldn't mine a b cup or at least a small c cup. Well right now I think I'm bigger than a c cup. Also it appears like I have too much loose skin on the sides under my arms. I go see my surgeon on Jan 2nd but I was just wondering if anyone had some answers.

Thanks Julie
