What is considered decreased movement?

I'm 35 and a half weeks and yesterday and today I've noticed decreased movement, but it's not to the point where I think she's completely not moving. She's had the hiccups once today for several minutes and I feel her move a little bit for 2 or 3 mins and then she stops. That's only happened like 2 or 3 times in the day. No more hard jabs or kicks.

Any clue if I should report this?
