I'm disappointed with my breast augmentation. I'm a week post op and I'm tiny already! Is this likely to change?

I'm a week and a half post op I got 350cc over the muscle hp mentor implants I was an A to start with one breast has been larger than the other from day one which I know can be normal but the other breast Is very small in comparison the larger breast looks lovely and Is exactly what I wanted ive no money for another ba and I'm embarrassed to show ppl are they likely to change or should I get used to the fact ive wasted my money?? I'm a 36 back, I asked for 375 and he said no.
