Does anyone have any experience with these OPK's? I have been using the dual hormone one, had 4 flashing smileys (high fertility) than on Friday morning got my solid smiley (peak fertility). According to that I should have ovulated 12-36 hours after. I just did one of my cheapie OPK's and it's looking positive....so does that mean I haven't O'd? Can tests stay positive even after O has happened....this is driving me crazy, seems like the BD that I times around the 'solid smiley' was now pointless!
