Yellow mucus bowel movement

I've had colonoscopy's before, but this is the first time I had a yellow mucus bowel movement about an hour or so after the colonoscopy while I was in the recovery room before being sent home. I sure hope that stuff wasn't in the colon while he did the procedure. Right after the procedure my doctor told me I had a polyp and I should have another procedure done in 5 years. Anyone here experience this type of bowel movement soon after a colonoscopy?

It wasn’t with any stool just a lot of yellow mucus.
