The Two Week Wait

I am now in that two week time period after ovulation, but before I test or CD1 arrives. It is a time where women question every ache and every pain that they have. It can drive a woman crazy. At first Fertility Friend (FF) said I ovulated on CD14 which would have meant great timing for us. This morning, FF changed it to CD15 and I cannot figure out why. There is no good reason. The big problem is that I have been waking up early and having to take my temperature between 4:15-4:45 every morning for the last four days. I took it again this morning at 8 and it was .20 lower. Perhaps it is time for a new BBT or new battery if I can find one.
