Nausea at 36 weeks all of a sudden?

Rachel
I haven't been nauseated all pregnancy except for a few weeks of my first trimester and all of a sudden today at 36+2 I've had nausea come and go. Just wondering if this is a sign of labor coming in other's expriences? I've read it could be. I've had a huge increase in discharge (no blood though) and painful BH the last few days.
