Oh my, I say you just need to run with it and don't worry too much about what the OPK's didn't or did show up. They could have been a faulty batch or anything.

Try and keep positive (seriously difficult I know!) and just get to the next blood test tomorrow and see what happens.

I am so excited for you, I know how much you have wanted this - I really really hope it all goes to plan.

Big hugs, and fingers crossed!
