Less movement??

Joei

So I'm 24w5d and my baby has been a little less active the past few days. I have a doppler and her heart rate is perfect. But it just seems like the past 3 days she's been moving less, now shes been moving just not as much as she was a few days ago. Should I be concerned? Go get checked out? Or should I just not worry about it?? Ive ready that you dont have to count kicks until later into like 30 or so weeks. I'm just a curious and slightly worried momma! Any advice will be appreciated.
