STILL waiting on O for this cycle.
I am new to OPK, checking CM and CP too, but here's my observations:
I've also found the the lower part of my cervix tends to be quite a bit softer than the top part. I'm usually confused about cervix position and texture, but as the PP said, I understood this cycle when it got so high that I could barely reach it.
As for EWCM, mine is usually streaked with white. It's rarely ever completely clear. And when I have EWCM, I also have creamy CM at the same time.
Hope that helps!
