Movement

Okay so for the last like week or so my baby has been moving less. Like he doesn’t kick much at all and he just rolls slowly now. I’m 34 and 3 so maybe he’s running out of room? I have an at home Doppler so I listen to his heart beat a lot but idk. I’m getting nervous. I see my doctor on Thursday should I just wait till then to mention it or should I call sooner? Or is it even worth mentioning??? Ftm so basically I’m just paranoid about everything😅
