When it is close to ovulation, which comes first? LH surge? Or BBT dip?

The title is my question. I'd appreciate if anyone could share their experience or charts. Thank you!

My bbt for few days is excluded as I've had restless sleep.
I had a LH peak and BBT dip around the same time

I don’t know because on one cycle I had a dip but on another I didn’t. I will attach a photo of the cycle I conceived my son in 2022. I had the lh peak on the Sunday evening so I think I ovulated on the Monday or Tuesday morning at the latest. I didn’t have a dip that cycle. I did the one before though.

Well I guess the Sunday to Monday is a mini dip actually. I got the peak on the Sunday evening, so the lh came first for me in the cycle above.
