Decreased movement?

I’m 24 weeks and started feeling baby moving around a few weeks ago. He has been really active and I was feeling him all the time. Especially after eating and drinking. Over the past few days it seems like he has really slowed down. I used my Doppler and his heart rate is still good, but I’m making myself panic. Has anyone else experienced decreased movement or should I call my doctor?
