I've been BBT for about 8 months now. And I had clear signs of lows and spikes. But not lately. I've been waking up at different times, just because or to use the restroom. When I wake up I can't tell what time it is, so I just reach under my pillow and get my thermometer. Then I open my phone to realize I'm up early. Some times 2hrs before I have to wake up & some times 30mins. Of course I go back to sleep and end up taking my BBT again. I'm not sure what BBT to enter. This is getting frustrating as I'm not seeing any clear spikes. This morning it was: 98.56 @ 5ish am and 98.36 at 7:20am.
