Should I be concerned?

I haven’t felt my little boy move since earlier this morning. I have my days and nights mixed up pretty horribly right now. So i slept from 10a until about 6. He usually wakes me up kicking and moving around. I am 26 weeks. And the things that usually make him move (such as eating for laying down) hasn’t made him move. Should I be concerned? I did manage to get a little movement just now when I lay down. Does that mean he’s okay? Can I be sane again? Is he just napping?
