Missed ovulation?

Ka
So this is my first month using OPKs, and I have to say, I'm a little discouraged. I've been testing basically since my period ended, and this is how every single test has looked. I'm now on CD20 and I have CM that aligns with ovulation and symptoms that align with ovulation, but absolutely nothing on my OPKs. 
Do I give up OPKs and just go with BBT and other symptom watching? Or keep testing?
