I was like you Gecko with the about to head over to the 6mth+ thread thing.
I was charting on FF (temp, and CM) mostly because I was still getting used to my cycle after coming off BCP for 9 years and I hadn't paid attention to what it had been like before that. I had noticed that my temps were a little on the low side and thought I'd try acupuncture to try and raise my temps - started in the middle of my cycle near where I o'd and my temps jumped the next day or so (was also given some horrible tasting Chinese herb mix as well) and that was the cycle I got my BFP. Discovered the BFP the next week as I thought I should check if I was pg before going back for my next apptm particularly as I knew that it was around my O and my temps hadn't dropped yet.
