Bitterly disappointed by breast augmentation results. Need advice

I had a breast augmentation done about a year ago. The surgeon said she recommend 500cc silicone round smooth, high profile under muscle She said it was a large implant, and I should be a D cup. Once done, I was absolutely thrilled, however 3 weeks later when the swelling went down, I was shocked how small I was. In fact, I can still fit in my B cup size bras, and even measured with tape and I'm still a cup B. My mom and sisters told me they see absolutely no difference in my clothing.
