My basal body temperature is odd. At the beginning of my fertility week the temp drops down to 97.1 and then varies throughout the week between 97.1-97.4. On the day Glow says I'm most fertile it goes up to 97.8. Back down the next day. Then after my fertility week it goes back up to 97.8/97.9 and it seems to say up in that range until I get my period, then it goes up to 98.1 to 98.5. I have been taking my temp at the same time every morning before getting out of bed. Nothing in my environment has changed. I'm in my mid 30s.
