I'm doing my Progesterone BW later today. I'm doing it the standard CD21 since I really have no idea when or if I O'ed. (Normally CD21 Progesterone BW is done 7 days after O, not so much on CD21, which is just a guess for the average women that does O on ~CD14.) I have a feeling it's going to be pretty low unless I really did O at some point.
I gave up on the OPKs this cycle. O then after CD20 results in a spoiled egg. So there is no point in continuing.
