Why OPK's should never be used for TTA!
This picture is of two opk's that I took within hours of each other!! The first was not really even close to looking positive. I took another opk two hours later because I was feeling a little crampy and it was super positive! If I would have been relying on opk's alone, I would have been in BIG trouble. Now I just have to hope that us BD'ing a couple of days ago keeps us in the clear I have had no AF for over 4mths and had no fertility signs whatsoever a couple days ago. Anyway, just thought I would share how quickly OPK's can change!
