Almost Over

Today is almost over, and I don't know if I am looking forward to tomorrow. I used one of my left over opk's and it had no second line AT ALL. That has never happened before, but I am looking at it as a bad sign, even though I am only 12 DPO. I have been having some cramps today in the last few hours and am praying that it is not the beginning of af :( but I'll find out soon enough I guess. I hate how this has taken over my life and my relationship. It's like I have failed as a woman.
