Super scared!!!

So I haven't felt baby the way I would normally feel her. She would move every night from 2-4 12-2 and 8-10 I'm 24 weeks and Idk what I should do I've tried cold ice on my belly to get it cold for baby to move to get warm. And juice and still nothing. Maybe I felt like 4 movements from 1am till now not normal for her should I call my OB
