Missed ovulation i think?

leilani
So I was supposed to be ovulating this past week and I have tested every day since wed. I have yet to ovultate. In the mean time my temp is increasing as well as more headaches as well as hot flashes. I mean they could be pre sign of ovulation but not for sure. My AF is not supposed to start until mid April or so. Has anyone else delt with a missed ovulating time frame, or I'm keeping the faith that I have finally will get my bfp.. Hmm.. Any opinions out there
