I think you feel all sorts of strange sensations in your boobs in the first few weeks so i really wouldn’t worry. You seem to get a new pain or ache or sensation every day. Maybe you can feel when they drop but i don’t think i noticed, only by seeing the change every week. I really wouldn’t worry too much. They do say to treat each boob like seperate operations so if one if dropping quicker than the other than it’s completely normal xx
