AF Late but discharge?

Marina

AF is 5 days late and I am testing negative. I’ve had a regular cycle with ovulation every month so it would be out of the blue if I didn’t ovulate this month (but I didn’t confirm that I did). Have had no symptoms of AF but I started having very sticky, stretchy CM today, and I don’t usually pay attention to CM so I’m not sure how to interpret it. Could this mean I ovulated later than I thought this month? Any help is appreciated!
