There is no way to really tell by looking at the cervix as it changes at different stages for different women but generally it goes back down to low and closed when not fertile and af is coming. The white cm could be a sign of pregnancy as I have it but didnt get it that early but again every one is different. I think it is definatley not to early to test now is the best time to test once af is late you get the best result. Let us know what the result is! How exciting is this planned or a suprise!
