So I’ve had a very light bleed for a couple of days. This is a few days before my af due. Very minor, nothing on pad just when I wipe. I thought it was af coming however stopped today. Lower back ache which made me think af and twinges to right lower abdomen last night. I’ve done a test tonight on 2hr urine (I know I should wait til morning) and will retest. Can anyone see a faint line? It came in allocated time and is full width of line but one part darker than the other. Could this be implantation bleed? Any similar stories with all outcomes welcome
