So lost on how to choose the right size & profile for my implants (Photo)

30's, 5'6", 125lbs, narrow frame. 34B. Had a consult last week for a breast augmentation. After trying on the implants, I ended at 700cc high profile. Now I am doing more research and am worried that will be wayyyy too big for me. I think maybe a D-DD would be an okay size? Maybe E? But, I don't know what that would translate to in cc's. Also unsure about mod v high profile - high was at the doc's suggestion. I want larger than average but not crazy big.
