Temperature charting help

So I have a question in regards to my basal body temperatures. Yesterday morning I took my temperature at the usual time, I had been a tad restless in bed an hour prior to taking it, and it was 36.3 c (97.3 f). Later that day I noticed I had extremely fertile cm, and that night baby danced with my partner.

Now I live in a warm environment, it’s about 30-35c most days (86- 95 f), so not cold and I had just been busy baby dancing.

I randomly decided to take my temperature when I jumped into bed out of curiosity to see how much higher it had gotten, it was 35.9 c (96.2 f).

So of course I’m super confused as to why the temp drop and if I should just disregard the mornings temp? Super weird.
