So I did a OPK yesterday lunchtime and got a dark line - not quite as dark as the control but even when I surge it's never quite as dark. Obviously I think I'll ovulate today. Then just for interest I did another lunchtime today and the line is even darker than the control. Which would surely say it was actually today I had the surge.
The thing is my EWCM has dried up, and my cx has dropped and is now closed. I know my body pretty well and that normally signals the day after O. So by my body yesterday was the surge.
So which day did I get the surge? I'm starting to think these tests are more confusion than they are worth
