If you were my surgeon what would you do? Please help! Any comments will greatly help me.

Hi I am 5'7" 140lbs ,30 yrs old, broad chest. I had my first BA 2 years ago and was concerned about going too big. My biggest concerns stretch marks when I get pregnant and breast feed. I picked a highlhy known surgeon. I woke up with 450 cc style 20 submuscular inframmary and came out too small. So 8 weeks ago I had another BA and he used 700 SRX. :((((( I look like I have too much breast up on top and not enough on the bottom. I am soooo devastated. I followed everyones suggestion to go big.
