Is it okay to lose 10-15lbs after Breast Augmentation, without my breasts changing?

Last week, I had a breast augmentation. 500 and 475 cc, HP, silicone, under the muscle. I currently weigh 125 lbs and am 5"4'. I realize that I should have reached my goal weight prior to the BA, but unfortunately failed to do so. My breast size pre-op was a full 34A. I am not sure if I lose weight in my breasts - I think I usually lose/gain in my abdomen and face first. I know it is hard to say, but will it be okay to lose 10-15 lbs with my given stats without my breast changing? Thanks!
