Clueless First Timer

Sorry for the long post.

The past week I've been nauseous, lost my appetite, had diarrhea (sorry), been experiencing increasing Braxton Hicks - both the frequency and intensity have been increasing, I've had significant pelvic pressure, been peeing like a fountain, consistently losing my plug and I'm not as bloated (my skinny face is back).

Should I be getting ready to go into labour or do I still have a couple + weeks?
