N2l - have you ever temped in a cycle? Do you know what your BBT is like before and after ovulation? Sometimes I dont temp during a cycle because it's a PITA but I know my pre and post ovulation BBT 'range'. So occassionally I might take a temp to just check where I'm at. I've done this after mc/birth when things get delayed. I wont temp every day but if I'm wondering what's going on I temp for a couple of days.

Obviously that wont work on an annovulatory cycle but then temps are usually so up and down on them which can tell you something in itself.

I hope you get some answers Friday or AF arrives.

I can recommend a fertility acupuncturist if you're interested.
