Less movement normal?

Jenna
I babysat a child on Friday. He was 2 years old and a bit rambunctious. He would get a little wild and accidentally hit or kick my belly. Ever since I've been a bit sore and feel like my baby is moving less than usual. I'm almost 32 weeks. At first I figured as long as he is moving it is okay... but now that the movements seem less and lighter I'm getting a little worried. Am I being too paranoid since he is still moving or go to the hospital to be safe? Or is it pretty normal to have less movement sometimes? I still feel hiccups quite often. I just don't feel those belly rolling movements. I have my next doctor appt in 5 days.
