Waking up multiple times at night, which bbt is correct?

Just after some advice. Recently I’ve been waking up multiple times at night worrying that I’ve missed my alarm and have forgotten to take my bbt 😂 paranoid much?

My alarm is set for 6.30am every day but today I woke up once around sunrise as I could hear the birds singing but I didn’t check the time and quickly took my temp which was 36.33 Celsius and then went back to sleep. Then my alarm went off and I took it again and it was 36.41 Celsius. Which one do I take as correct?

Does this happen to anyone else? How do they usually decide which temp to take as correct?
