Confused about my cm (tmi)

Katey
So I've been checking my cervical mucus and yesterday afternoon it was cloudy and stickyish I guess would be the best way to describe it. Then last night right before I had sex I went to pee and when I wiped a good amount of clear, egg white very fertile looking cm was on the toilet paper. I stretched it on my finger and it was like perfect fertile cm. How would that be possible when 5 or 6 hours before my cm looked completely different?
