Anyone else have irregular cycles and low temps?

What is this SH*T?! my temps are always so low and I thought I Ovulated on Feb 19/20 but guess not? Maybe I don't O at all? Never got a positive OPK so I stopped using them. Anyone else have issues like this? what was it? Is it my weight,pocs....

this is from a few days ago when I was told I probably Od. sorry I wrote on it. I snapped it to the hubby so he could follow along, he was at work when I got a response.
