Hey,
I’m 11 weeks post op now, but it took my right 2 weeks and my left 6 weeks to drop and fluff, so they definitely can do it at different rates, at the time my left was considerably higher and looked tighter. Did you have a 3 month check with your surgeon? I had mine (although a little earlier) and he said I’m obviously an incredibly fast healer so it could be that it just takes a little longer with others sometimes.
Give them a call if you’re worried.
