Breast implants dropping - 11 days post op 345cc teardrop, under muscle. (Photos)

I'm currently 11 days post op 345 cc teardrop under muscle, and to me my breasts are at my ideal shape size and position on my body. They have already changed so much since my surgery and I am worried they will continue to drop for another 2-3 months, and by then, may look a bit saggy. My Surgeon did explain to me that they should only drop about 1cm so I guess I wasnt expecting them to change too much. Any information in what I can expect over the next few months would be greatly appreciated!
