Is labor near?

Amber
I'm 36w3d and I've been having sharp paints in my back and m lower belly. A bit of diarrhea and my stools are soft. I had false labor at 31 weeks. My neusea has returned. I'm always uncomfortable because my son has ran out of room in my belly. He has also already dropped. I have lost part of my mucous plug. Could labor be near?
