YOU NEED TO GO STRAIGHT TO A DOCTOR.. THIS IS NOT NORMAL YOU MAY HAVE SEVERAL THINGS WRONG I WOULD MAKE APP. FIRST THING OR GO TO THE EMERGENCY ROOM YOU MAY HAVE A OLCURE I NOT SURE HOW TO SPELL IT BUT THIS IS VERY SIRIUS. I HOPE YOU TAKE MY ADVICE AND GO.. MAY GOD BLESS YOU AND HEAL YOU ..
Agreed with Lynn, you MUST SEE A DOCTOR NOW! Could be as minor as hemeroids or as major as colo-rectal cancer. Extreme bleeding from any point on your body is never something to ignore!
I hope by now you have gotten some type of care for this. It seems like you have a serious GI bleed and need to be seen right away to find the source of the bleed in your GI tract and have it addressed right away!
