Is it normal for my left breast to look different than my right after 3 weeks post op breast augmentation surgery? (photo)

Without any photos, there is no way to reliably pick which implant is right based upon your measurements alone and implant "CCs." Many things such as your skin quality, breast width, skin elasticity, existing breast tissue, chest wall shape and implant size and implant fill all contribute to...

In my opinnion, you are starting with a good B cup.  In general, 150-200cc is a cup size, so adding nearly 400cc will certainly overshoot being a full C!  Maybe look at a lower profile implant.  That would reduce the volume and not overwhelm you.  Good luck!
