TMI! yellow Cm looked like snot

Anyone ver experience this? I woke up to use the bathroom and when I wiped it looked like yellow snot and was super stretchy tmi lol sorry. I could only see it when I wiped. Was 56 days into my 28 cycle and I finally had a period just ended three days ago. Period was longer than normal and lighter as well. Had sex the last three days as well.  It's not an infection there is no odor and no green tinges. Just wondering if anyone experienced this and what it was?
