Uneven Breast Augmentation? (300cc Mod Profile Implants)

I underwent breast augmentation to fill out clothes better and to make my body more proportionate to what it was before. Now i finally have cleavage!

I was a large a /small B cup preoperatively. I am now one month postop. Ive had 300cc mod profile implants inserted and am curious as to what size i will turn out to be approximately? My left breasts seems to be slightly assymetrical too. The left is slightly fuller but they are both the same in feel. They are quite firm still though soft around the nipples. The breasts do not come together yet and are sitting quite perky. I just wanted to know if they will ever drop over the crease?
