It appears that my temperatures are steadily rising... Maybe it'll be a tri-phasic chart. All temps (except for the one on CD3) were taken within 10 minutes of my usual time, the vast majority taken at 5.50 a.m. and the others were taken at 6 a.m. They should all be pretty accurate.
Oh, and I did test again today... It seems I'm a testaholic! Negative as expected. Maybe tomorrow will be a really faint positive, that's what I keep telling myself anyway! :-)
