Bbt took a dip on 2dpo?

Hey ladies, I did have a bit of rise below average on 1dpo, but this morning I was expecting it to be even higher but instead it was 36.23. I mean it is still somewhat above average cause if you see bbt on Dec 1 it was 36.24 (this was exactly 6 days ago). This never happened before, I usually always have a rise on 2dpo. This is just so upsetting for me especially I’m going on a trip today and thought I didn’t have to worry about this.

Do you think this indicate failed ovulation? Or perhaps anovulatory cycle? Or I could still have ovulated and my bbt could rise again?

Also what’s weird is my Apple Watch gave me a 36.45C reading for my wrist temp overnight.

Need some experts opinions please to calm my mind 😞 thanks in advance.
