For about a month i have bren having a dark brown discharge. Prior to this, my last cycle was August 2012. December 8th 2012, I went to the doctor and they couldn't seem to figure out why i haven't been having a cycle, but prescribed some birth control pills that was supposed to restart it. I havent taken them, in hope that my cycle would start on its own, which it did March 4th of 2013 (This Year) now, i would bleed on and off and i havent bled in about a week or two. NOW, i've been experiencing brown discharge.. any idea what this could be?
