Mucus plug?

So sorry if this is TMI but I had a dr appt on Monday and I’m 3cm dilated. I’m scheduled an induction on the 18th next week but was told it’s very likely he could come on his own before hand. I’ve been having contractions but nothing close enough to even assume labor is close. I have a gut feeling I won’t make it to my induction. My question is does this look like it could be my mucus plug?? I sat on the toilet and felt/heard this come out and it’s chunky so I’m confused.
