Mucus plug vs bloody show

Carli
Is there a difference? I can't decide from what I've read online. Just had a mass amount of bloody mucus. It was really just blood with mucus consistency not just a streak of blood. I had mucus last week I believe was my plug. It just had one streak of blood in it. I put a call in to my dr so I'm waiting to hear back. Had the worst contractions of my life from 12:30-8am. "2cm and a wiggle" dilated according to triage last night.
