Help with ovulation test please!!

[sianii]

Hiya, I'd really appreciate a bit of help, iv been using a clear blue ov test since day 6 of my cycle and 2 day is only day 9, I have pcos so I have no idea when I ovulate, iv have bfn until this morning when I got a smiley face to say I'm ovulating, but I took another test 2 hours later and it was another bfn??? I'm so confused! Has anyone every had the same problem and had success at becomming pregnant or anyone got any ideas why it has gone so quick, I am desperate for a baby, thank you, Sian xxx
