Very important, please read soon

Okay so I know this is probably a weird question.. but I can't seem to find any information on it online. I just recently, like a few hours ago realized that I've been getting normal need-to-go-to-the-bathroom cramps, but when I went, I noticed that it ( my poop ) was green. like very grassy green not like normal. and I bled a bit. what could this be from? please help if you know I'm worried it's serious.

see ya post about anal sex..... that can explain the blood ..... and the green slim well what did ya eat .... whatever it was may not agree with ya system .... cramps aren't normal but aren't that weird either....... ya body is a marvelous machine .... give it time and it will probably heal itself...... still having problems a week from now .... go get it checked out...... criss

Dear jennipherr,
Do not wait...go see your doctor right away...when the stool is green that sometimes means nothing but indigestion and a little blood could be from forcing yourself. But blood in the stool is one of those things that has to be checked out immediately. Also try to remember what food you ate...was it green? Was it something different?
Sue...good luck

Have you been eating blueberries, or blue cool aid, or anything else blue that might color your stool?
