Ok forst off, I NEVER get true +OPKs on the progression line OPKs, so I use digis to back them up, if i think I have a +OPK. I am using the Walgreens brand OPK, since Wed everytime, I test, The Walgreens has been + day, afternoon night. The CBE digi gave me a smiley, Wed afternoon , it was my last, one. I usually have short surges NEVER more than 24 hours MAX, but the Walgreens is still giving me +OPKs and the CBE digis (I bought more) is an empty circel with the same urine. I decided to buy more digis yesterday, because I was feeling something wasn't right, today would be my 4th day of +OPK, yesterday the Walgreens said +, the digi empty circle, here is a a few pics. What is going on?, I took out the +OPK yesterday on FF because I don't believe it now. Can anyone make heads or tails of this, plus my temp is going up, I think I O'd on Thursday so I will have to see tommorrows temp to see if FF gives me crosshairs.Any advice it greatly appreciated.
