When do you think I ovulated?

I know I am missing lots of post cross hair temps but this month once ff was "sure" i ovulated i said i would stop temping everyday so i didn't obssess. Took an early detection test today completely negative. My LP is usually 13 days 🙁

Also I have PCOS so don't bother with OPKs and a bit of spiking up and down is normal in my bbt but FF appears to have been right for the last six months as my period has always arrived when it said it would.
