My cycle was due January 3, 2012, it didn t come on. I took HPT, negative. My cycles have been irregular so I did the menstrual cycle predictor, cycle due on the 9th. On the 9th, I experienced brown blood when I wipe. This lasted for 4 days. On the 13th when I used the bathroom there was red blood on the tissue and the commode water was red. Now sometimes I wipe blood nd sometimes I don t. Sometimes there is a little blood in the commode and sometimes not. At first I thought it was implantation now I don t know!!!
