CM changes

Sabrina • Married my BFF 02/2014! Been "actively" TTC#1 since June 2014.
Does anyone else's CM change through out the day? Like today, I woke up and felt dry, then noticed creamy CM, and now, it's sticky and clear like egg whites. I am in the fertile window, and maybe ovulated on the 5 or 6, just waiting for my temps to confirm it. I'm just not sure which CM do you chart if you notice it changing throughout the day?
