OPKs have become the bane of my existence.

Flipping back through my app - I did get a positive for a day in March and April (on day 16 both times), and then not a positive in June or July, but didn't test consistently (scientific mind talking - controlling for dilution of urine, time of day of testing, etc.). I also was using Clearblue Digitals this cycle, which I've since been told are kind of the suckiest of all the tests to use (#1 recommended by OB/GYNs, my tuchis. I'm a breastfeeding counselor and should know better than to fall for that marketing!). So. Seems like all is probably well in my babymaker and that I shouldn't worry too awfully much about not being able to get pregnant just because a stick isn't showing the line I want it to!

I honestly think the OB's don't see anything but a pretty package with the Clearblues. We have to keep in mind that for most people TTC, they just need ballpark when to DTD and Clearblues are relatively adequate for that "just DTD every other day of high and then every day of peak" but those of us using them for timing or pinpointing ovulation, they are not good enough.
