I've been using the clear blue digital advance OPK and gotten positives the past 9 days. I used my cheapy OPK from dollar store on Sunday and had 2 solid lines. Then woke up the following morning with the solid test line was super faint, but my clear blue advance is still flashing smiley faces. Anybody had this issue with the clear blue advance? Or going through the same thing with these OPKs? 9 days of flashing smiley faces is a lot and the lines on the sticks don't match up :( I have a 28/29 day cycle and usually ovulate around day 11/12/13 or so I think. Should I just ignore the clear blue test??
