I missed my period for a month and half then was getting smear of blood when I go to bathroom. But since I had colonscolpy (which three polys were found and taken out) last week, I've been bleeding a lot. I may be menstruating but I have a blood flowing like a river. I was in the emergency yesterday- blood test, urine test, ultra-sound,... but I was healthy. I am now referred to OB doctor to see what's going on. Do you have any idea?
