Has anyone noticed any consistent patterns with their CP?

I know I keep reading on here that checking your cervical position is not the best mode of tracking, but I'm gettin worried. I'm 3 days late today and I'm planning to test if I go the rest of the week without AF showing up, and I read that your Cervix is usually high up, a little fleshy/still hard, but closed tight when You become pregnant. Well for the last few days it has been high, tight and closed in the morning then drops lower in the evening. And this morning it is now low, very very soft and starting to open a little bit :/ is that a bad sign?
