I had my last "normal" period on 11/22/10. Then I had "spotting" when I wiped(pink, not brown) for about 3 days starting 12/3. I did not have any other bleeding during the entire month of december. This got me concerned as I have never been more than 31 days in a cycle and ususally are around 23 days average. Well I took hpt and it was negative and even took a blood test at the doctor and it was negative as well. I have an appointment with my ob on Feb 1. Well on 1/7/11 I started lightly spotting again and did so until today. Very light barely making it to a pad and none in toilet. Usually my periods are very heavy lots of clots and cramping. What could be going on. I cant stop thinking about it...
