Mucus plug? Thought my water broke? 38 weeks

Okay so I have had pretty heavy discharge me entire pregnancy and a lot of watery discharge as well. To the point I thought I was leaking fluid but my OB said I wasn’t.

I was just sleeping and felt a little bit of a gush sensation? But nothing crazy! So I stuck my hand down to feel and it was wet, and odorless, which is not like my discharge I had been having. So I sat up to see if maybe i would feel a trickle or more liquid and I didn’t, however I do have a small wet spot maybe the size of a quarter in my underwear?

I went pee and then this was my discharge, similar to when I had thought my mucus plug, only the other day it was very jelly like and definitely looked like mucus lol. Could what I felt be the remainder of my mucus plug? Should I call my doctor? Not having any real contractions? Just my basic discomfort as normal. Hip pain, back pain, pressure in the back, uncomfortable to move, etc…
