Hi Zoe, I have something similar with my left one. I am much more aware of the implant in that one whereas my right now feels likes it always been mine (6weeks post op also over the muscle) When I bend over I feel it, not around my nipple but high up and in my cleavage area. I wouldn’t say moving around but definitely feel something. I think it’s just the implant rippling until there’s more space, at least I hope so. My left was naturally bigger (by a tiny bit) and my surgeon used the same size implant, I think it’s just taking longer to settle for that reason, skin needs to stretch more for implant to fully soften and relax. Here’s hoping anyway. If you get checked over and it’s something else do let me know xx
