Thanks purple, I don't know. It fits with a lp of 9 days, which seems to be usual for me. I am temping but started temping vaginally since af, I am hoping that will be more accurate but not sure comparing it with oral temps would help. Am cd 6 today so am going for an attempt tonight as have decided to move on to e4d's as opposed to one attempt. What is " not real period"? thanks x
