TMI - mucus plug

LT
So this weekend I was having some contractions. Went to triage, got monitored for a while. They eventually stopped, baby was fine. Not dilated, but cervical check showed some softening. Today I wiped and this is what I had. I have read a bunch of conflicting info on the mucus plug, from it being the sign of the start of labour to it being nothing but just discharge, and will regrow. Just wondering if anyone had something similar, and what was your experience.
