Is it an emergency? Or am I over reacting?

I am 33 weeks along and today I noticed baby hasn’t moved as much. She was more active this morning and as the day has progressed it’s been less and less. I don’t think I have felt significant movement for about 2 hours now, and for the past 6 hours the movement has been bare minimum. Usually she is kicking me so hard my entire stomach moves. Her movements today have been really soft, and I am having a hard time noticing she is moving.

Should I be concerned? I mean my mind is going a million miles a minute
