Baby not moving as much as normal?

I drank cold orange juice and some coffee and ice water this morning which normal makes my son bounce off the walls but he’s barley moved at all. He always moves around this time but today he isn’t as much. He’s moved his legs around but hasn’t kicked. He’s been extremely active the past few days and I had my glucose testing yesterday so I don’t know if the sugary drink made him so active yesterday he got wore out today, should I be concerned or is it ok? I’m 28 weeks
