Arrgh. It also drives me crazy that I messed up my temp on day 15 so I have no idea what day I o'd on. But I ahd a faint OPK on the cd14 and a dark one on cd15. I think maybe I O'd on cd16...what do you guys think based on OPK alone. Bunny I can't believe that you get so many postive OPK's in a row! Meds?
