Breast Augmentation 3 Weeks Ago and Have Movement in Left Breast?

I just had breast augmentation on Aug.3 and my right breast seems fine, however the left it seems as tho when I move my arms something moves not sure if its the implant or if this is normal.. I am wondering if I should go back to the dr and let him know or if this is normal and will pass.. It's not the whole implant moving kinda hard to explains what it is I feel but I am in no pain just annoying since I dont have that problem on the right.. Thank for your time
