Thanks so much, very helpful!

Reason I asked is that I have been TTC since December 06 and have been trying to pay close attention in this area to learn when I am fertile etc. AF due in 5-6 days and I still have a lot of creamy CM and have had cramping the last 5 days so am just hoping for you know what :-) But, knowing my messed up system I will get AF lol..
