What Jennifer said, a significant change to something much drier is required - but it doesn't have to be total dryness/no CM. However, this is all based on external CM observations.
What you find at the cervix is not the most accurate reflection of your fertility. First of all, there is always some discharge and moisture there. Secondly, during the infertile parts of the cycle the mucus dries up at it passes through the vagina over glands called the Pockets of Shaw. Going in to search for mucus internally disrupts that process and can make a woman mistakenly think she has more fertile days than she actually does.
If you do like having the cervix sign, it's best to check it at the end of the day after you have already made all of you external CM observations for the day. Check the cervix for it's position and firmness, but disregard any discharge you find in there.
Hope that answers your question!
