Hi all! I'd appreciate any ideas in regards to my health concerns.

The past four menstration cycles, my stool is black, tarry and very runny. Sometimes it's dark green. I also have had a lot of gas everyday for many months and this is very abnormol with my history. I rarely take iron pills and in the past even when I took them regularly, my stool was brown.

Four months ago when the black stool started, I was very weak and showed many symptoms of anemia, as I have experienced off and on for eight years. I went to the doctor, and they found no blood in my stool. They took a blood test for anemia but my results came back normol except that my white blood cell count was extremely high. They think I had a virus.

I commonly have runny stools especially during my menstration cycle, it's just during menstration it's been black or dark green for the past four months. And I haven't had any pains or weakness for three months.

Colon cancer runs in the family.

Anyone familuar with this?
