baby movements?

Hi ladies. I'm 24 weeks with baby no2. And in last 2 days he hasn't been as active as usual.. still feel him kick and move about. But he doesn't kick out anymore and I have to lay there for a while before he moves.. worries me, have been busy the last two days and constantly on my feet, but I can't help but panic when I don't feel him for a few hours because it's pretty unusual.. is it something I should be worried about and mention to doc, or is it normal?🙄😑
