BBT Question


So, I have just begun taking my temperature in the mornings when I first wake up a couple of weeks ago. I plan to wake up at 5:45am every day since that is when I get up for work. Sometimes, I will wake up an hour or 2 before time to get up for 5-10 minutes and go back to sleep. When I wake up like that, should I take my temperature then, or wait until my planned time everyday?
