Hi surgeons, I am currently only early stages post-op (3.5 weeks) with an amazing set of Mentor 322 anatomicals (love them). I opted for 420cc but had minimal tissue to begin with post-children, fitness regimen etc., and so am noticing the tightness of my new breasts and am very keen to know when (if at all), do implants start to move and jiggle when walking? Thanks for your input.
