Is this a piece of mucus plug?

I’ve had cramps and a backache since 12:00 yesterday. I got checked and was a fingertip dilated yesterday afternoon. TMI, but today I’ve pood at least 4 times 😬 and this is the 2nd time I’ve wiped today and gotten some of this. Does this look like a piece of my mucus plug? I’m 37 +1 today.
