29 week baby movement

I’m 29+3 and yesterday my baby was so active.. but today has me concerned. i work two jobs so i have been up walking around from 9am until 10pm, with very few sit down breaks. and now that i’m off work i realized i haven’t felt him move very much today.. should i be worried? Also i didn’t have much time to eat, so all i had today was a sandwich and some fruit. An orange juice this morning and 2-3 waters. Suggestions to get him moving ?
