This is cycle 2 of us ttc & I wanted to start using OPK's since bbt is really not a reliable option at this point. I'm on CD 10 and TOTALLY forgot to pick some up earlier!

I was reading up on the clearblue digi & it say's to use fmu (I thought with opk's you *didn't* use fmu)... If I'm supposed to use fmu on these & I'm already going to be on CD 11 in the morning should I go get some now before bed?..
