So, I usually take my temperature at 6:30am. This morning, I woke up (naturally) at around 5:50. Nervous I wouldn’t be able to get back to sleep right away, I took my temperature and tried to go back to sleep. It was 98.19 at that point.

I fell back asleep and woke up again at 6:30, taking my temperature again, and this time it was 98.02.

Why would my temp be lower after waking up once already? I was under the impression that if you took you temp earlier than normal it should be lower than normal. Which temp should I take as accurate?

I appreciate any input!
