me too!
i was actually thinking of charting twice a day, a chart for my 1st waking temp, and then another one for the evening (as if I need anthing else to obsess over!) I ready that if u track evening temps on a separate chart, temping at the same time every evening and having consistent activity levels daily at that time, althought it won't be an accurate bbt, u should be able to detect a temp shift in that too. My goal in doing that is being able to narrow down ovulation from a 24 hr window to a 12 hr window. and it wouldn't be any extra work for me as I am known to have my thermometer stuck in my mouth and random times during the evening 'to see how my temp is doing'.
