BBT experts, help! What does this pattern mean?

This is my second month tracking BBT with a thermometer instead of my Apple Watch. Last month, my temps kept rising but then started dropping before my period (I suspect a chemical pregnancy—posted about it yesterday).

This month, my temp spiked high right away but then dropped. What does that mean? Poor ovulation quality? Or am I already out?

I’d love to hear your thoughts—especially from those of you who are super experienced and great at analyzing charts!
