Or part of it?

Back story.

Boyfriend and I had sex. He finished and I am already pregnant (37 weeks) and so, he didn’t pull out or anything.

I have been having some pretty regular, intense contractions since and its been about 2 hours.

I had a gush of liquid but because we had sex, I don’t know if it was just the remaining body fluids* even tho I used the bathroom (which has happened before) or if this is my mucus plug, or part of it. It looks like the google image but before I wake my midwife up, I was jw what you ladies thought.

I am only questioning it because it has a yellow coloring, but no blood or even pink.
