Just took another OPK after waiting 7 hours to pee and it was very very concentrated - I used a cup to make sure I got it well soaked and absolutely no line what so ever. Are you supposed to have a +OPK on the day you're ovulating? If I had to guess I'd say today or sometime tonight it is happening because of the twinges I'm feeling but the tests are all neg.
sorry for my annoying questions. So beyond frustrated with this month!
