While I idle away in the start of the 2WW....could use a little OPK tutorial if we have any experts out there...
Here's my timeline:
Wed 8/31 - OPK showed no surge (big zero face)
Thur 9/1 - OPK showed surge (happy baby face)
Fri 9/2 - OPK showed no surge (back to a big zero)
So do I assume I O'd on Thur...or sometime Friday? I tested each day at right around 6pm. The box just said that it would help predict the best 2 days to try....and we tried Thur & Fri (DH got sick so we didn't over the weekend), but I'm wondering if it's possible I O'd late Friday and missed possible window on Sat too.
Anyway, I'm bored so would love opinions or comments or commiseration for those also in the 2ww

I was thinking I could test as early as the 11th (yeah i'm a glutton for punishment

) but was mentally targeting lucky 13th...AF should arrive sometime around 16-18th.
