Ok so I posted a question about OPKs and it got answered but I have another question...for anyone near AF/pregnant and used OPKs. I got a darker line yesterday than I normally do when I use an OPK. It wasn't positive but it was darker than normal. I'm at best (I'm guessing) I have five more days until AF is due. SO the OPK detected SOME LH but not enough for a positive, and I took an HPT this morning...so anyone think there's still a possibility I am pregnant or do we have LH in our system before AF?
