Anyone had.....

Creamy cm while waiting on af to show? I went to dr for a pap today and she had to scrape off a lot of creamy cm to even get to my cervix. It was cultured and was not an infection or yeast. Just lots of (tad less than pudding consistency) creamy white cm. My period is now 3 (4 if you count the day it was supposed to come) days late. I told them it may not hurt to run a pg test but all my home ones have been negative so far. But had anyone had this? If so what was it?
