Hey hun like Imogen said its totally normal and your only 2wks post op which I’d really early.
Everyone heals differently so try not to compare yourself as difficult as it is. After day 10, I stopped paying so much attention to mine as it was driving me bonkers! It may help if you just look/photograph them weekly.
I reckon you should be more concerned if they looked the same after 4 ot 6 weeks but honestly they won’t! If ur wearing a breast band and/or sleeping at an angle they will defo drop! I slept at a 45 degree angle for 4wks. I’m 9wks post op and still sleep on my back and only go on my side for a little while. Patience really is key fxx
