I am scared

First of all I'm currently 36+4. So for the past couple of days of been having some mild stomach pains, not really sure how to describe it, kinda similar to hunger pains. But when I eat it doesn't make a difference. I feel nauseas and just out of it. And now today I'm not really feeling any movement, I tried eating something sweet and laying on my side but still nothing. (Couldn't do it for very long bc I'm at work.) I went to the hospital just a few weeks ago for low movement but just turns out I didn't know the proper way to count kicks. Now I do, and there's nothing. My stomach hurts constantly, I feel ill, and I feel no movement. Has anyone else experienced this? Is it just late pregnancy symptoms? Do I need to go to the hospital.. again??
