Is it normal to feel one implant move before the other? Is it normal to feel them moving at all? (Photo)

Hello! I am 3 weeks post op today and was wondering if it was normal to feel the implants moving. I have 225CC Mentor cohesive silicone gel implants place submuscularly. I feel my left implant move when I do certain arm motions (using a hair dryer, grabbing things from above, putting on shirts,etc ) and occasionally will feel my right move, but not as often. It doesn't hurt, just feels weird, and I was wondering if this was normal? Will it always feel like this when I move my arms?
