AA Cup to a C Cup with 300cc Silicone Implants?

I had 34AA initially. I'm 5'8", and 135 lbs. The doctor implanted 300cc silicone breast implants (sub muscular). I asked for C cups. Mind you I'm pretty flat. Post surgery I seem small. My breasts are the shapes of cones. Do you think that I will achieve C cups by what I began with and what was implanted? Is this what you would have implanted?
