I know how you're feeling...OPKs have been driving me CRAZY this month.
I've been using the Wondofo brand ones for the first time along with the Target kind I used last month. Nearly positives in the mornings (only on the Target kind), but then back to faint in the afternoon (which I thought was supposed to be a better time to test), even after holding it for almost 4 hours! I got 4 days of positives last month, so I know the Target brand picks up my surges.
Cervix is high and soft, and I've got some EWCM too, so Im not sure WHAT the heck is going on. UGH!
Why is it all so complicated?
