Is my baby being lazy??

Since yesterday my baby boy has been a bit lazy, didn’t move as much as he usually does. I felt him kick a few times during the day. And today he only kicked a few times in the morning and moved a couple times but has lot been active like he usually is. He usually moves around all day and would kick almost every hour. Is he just being lazy?? Or should I call my ob?

I’m 29 weeks
