Sounds completely normal hun, specially as you are only 4 days post op. My left dropped quicker than my right and still a little that way and I’m nearly 3 months post op. Just a waiting game I’m afraid, but if you are worried at all contact your nurse. In the mean time use some cocoa butter on the tops of your breasts to help the skin soften and the implant to drop, just be careful not to get it near your scars. Apart from that you happy with your new boobies? xxx
