Insane increase in movement - 38w.

I'm 38w, and I've literally been sitting in bed for two hours wide awake because she is moving so much, everywhere, and SO strongly. She is already quite the mover, but this is absolutely out of the ordinary. My genius self went to google for answers and of course there were a few downer responses... That it could be a sign of distress. Anyone have something similar happen? Would love some reassurance!
