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!
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!
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 ..
