Welp, AF showed her ugly face in the wee hours of the morning. So, I'm out this cycle, but I'm at peace with it right now. however, I would really like to chart my temps and it is not something I had much luck with this last cycle and I ended up just quitting about two weeks in. Does anyone have some tips? My biggest problem is some nights we sleep with the fan on, or the window open, or both, some nights neither...I even tried temping vaginally, but I must not have been consistent with my technique, because it was all over the place.
