Does anyone else never get a positive OPK? Has anyone who hasn't got any solid lines gotten pregnant?

I hate when people say it can take 12 months to get pregnant, it's not like you're building up any more fertility, your chances reset every month and you are back at square one.

We have been actively trying for over 6 months and am already bored of the tests. My day 21 blood test says I definitely ovulate, everything else is in good baby makimg conditiin, but there's never a positive test and never a baby. I'm ready to give up on the testing.
