TMI PIC // IS THIS MY MUCUS PLUG!?

La

This is my second baby but I never lost my mucus plug until hours before I delivered and it came out all at once. I was just sitting down (no underwear) and felt “wet” so I got up to get a pad and underwear and noticed this on my leg!?!? I have no clue what it is or where it came from. I’m only 29 weeks, could this be part of my plug or something totally random that stuck to my leg?
