Are you really thin? If yes, it's feasible that you could see movement on the outside although it would be unusual. I'm thin, this is my third, and I know what I'm looking for, and I still haven't even felt movement on the outside. Everyone is different though.
Also, not to be a naysayer, but movement at this point is low. Below your belly button low. I'm not quite sure how, physically, you'd be able to see "huge" movement from your vantage point?
