Sooo Sunday 22nd I had a couple hours of spotting brown blood. At first I assumed AF was early as I was due Weds 25th on a 28 day regular cycle but it soon stopped and was like I say a few drops. Wednesday AF didn't arrive and I tested this morning and BFN. I had begun to hope Sunday was implantation spotting as this has never happened before. I didn't track my ovulation this month so could it be that??
