Not ovulating?

Michelle

My cycle is between 24-27 days each month. My temps are all over the place (I just started temping again over the last couple weeks). I’m taking my temp at the same time every morning after plenty of sleep. I can’t figure out when I’m ovulating. I was using the clear blue advanced and switched to the regular clear blue digital. No LH surge this month at all and last month I never got anything but the flashing smiley face. I’m concerned I’m not ovulating. I’m fairly new to this so maybe I am

Just confused. I don’t appear to be getting the fertile CM either.
