Crazy temps on letrozole

Has any one had crazy temps while on letrozole? They were in the 98 range while taking letrozole so I stopped temping until after cd 7. Temps are still crazy up and down and I had a positive opk on cd 16 but my temps are so crazy that it’s not confirming O. I am still OPKing just incase but I’ve had negatives since cd 16.

Anyway.. has anyone had crazy temps while on letrozole? I’ve heard to disregard them but I want to hear others experience.
