What Causes Continuous Bleeding?

okay i m looking at 6/13/14/15/2014 for the bleeding to stop..as for syntoms.. her is what I can get Day 2 of my period when I have a bm before or after there is blood... with pain. I m wondering if it is Rectum Cancer or Colin Cancer.. Could it also be Ed-doh-me-tree-Oh.Sis.. Also I m having trouble falling asleep at late hours of the night from being high on sugar and from working the late shifts. so I kinda feel like it s more of a time my body is use to. cause i pass out around 3:00 ish in the morning.. Also the sugar has caused a form of anexity that makes my heart pound in my chest and makes me feel like I ll have a rupture
