Awake from movement

Movement has been keeping me awake at night. Anyone else experiencing this? My first son is nine and has been my only pregnancy before this current one and I can't ever remember having trouble sleeping because of movement. Then again I was only 18 so maybe I just slept through everything while pregnant if that has anything to do with it. But I lay here and can't sleep and all I feel is him moving. I know I'm not complaining movement is a good thing, I'm just tired!
