1st morning temp is used for a basal (resting) temperature and that's the only time that temperature is a reliable indicator of pre- or post-ovulation (if you work nights and sleep days, you test when you first wake up, of course!) As you may know, Shawna, you have to get a night's sleep, reach for the basal thermometer before you get out of bed or do more than roll over - slowly - and take your temperature then. You may not talk or pee before taking your temp. because those activities raise your body temperature. A basal temperature is also well below the usual "normal" of 98.6* as that number is for when you're active.
My pre-ovulation temps were below 97.5* and fluctuated slightly day to day. Just before ovulation there would be at least 2/10 of a degree drop, and the next day it would be about 98* or higher and there it would stay (with minor fluctuations) until my period came - or didn't because I was pg!
My doctor told me that if my temperature stayed "up" at the post-ovulation level for 3 weeks, I was likely to be pregnant. That sounds like a long time to wait, but it's just until you're a week late. As long as you're following the correct procedure and your temperature is "up", there is hope!
