Did I miss the surge?! Pics in post

Holly

Hi, so this is my 2nd month using OPKs, and I just wanted opinions...

Do you think my surge was CD17, but that it happened between tests? The lines finally started to darken, but now they are falling again, and I never got a positive...

If the surge was yesterday, that means ovulation is most likely today, right?

What do you all think?
