My periods have been messed up for as long as I can remember I was on the depo for almost 2 years I got off of it and went about 5 months without starting my period when I did finally start I would go a week and then stop a week that went on for at least 4 months and then it stopped for a month and I started again yesterday but I have had the worst cramps ever! I can't eat it hurts so bad when I go to the bathroom it's little blood clots and when your on your period you can like feel it flow well I had some up last night because it was flowing so much I had thought that I was peeing what could cause this
