I've been spotting for the last two days, dark brown in color, but I'm not due to start AF until Sunday and I'm usually very regular. Not to mention, I've never spotted for more than half a day before my period. POAS tonight, and BFN. Anyone else have more than a couple of days of spotting before getting a BFP? I'm trying not to get my hopes up, but I also can't help analyzing things that are out of the "norm" for me.
