I started my period on November 3 and it hasn't stopped yet. I thought it stopped around 13 days, just had light discarge, but then i started seeing pink/red blood again. Today I'm discharging big black clots, which I think is just old blood, and I have cramping. My periods are very heavy since they came back when my twins were about 11 months old. (They just turned 2). Usually they last about 7-9 days. The first 3-4 days are extremely heavy, saturating a Super Plus every 2-3 hours. Nothing ever this long. I am not on birth control. I have 3 children: vaginsl birth on 06/14/09 and C with my twins 11/02/11
