Baby not moving as much

28 wk 3d So today I’ve noticed my baby girl hasn’t been moving as much as usual. She’s usually extremely active to the point where it hurts and causes Braxton Hicks. Almost active 24/7. Well this morning I remember she had hiccups around 7:00-7:30am but after that I didn’t feel any movement until almost 3 or 4 then she moved a little bit and got hiccups for maybe 2 minutes (they usually last 20 minutes) and then no movement since. It’s almost 7 at night. I have an at home Doppler and picked up her heart bear pretty easily (148bpm) but still no movement. So I’m in the bath (she always goes crazy when I take a bath) and she still hasn’t moved. Should I be worried or is she just having an off day?? Should I call the on call doctor??
