Hello, After being constipated for about a week or more I started having severe cramps and gas. I then began to have small bowel movements that had blood in my stool. Sometimes it was bright red and others were dark colored. I took a laxative and this helps relieve some of the pressure but I am still having pain in the same area of my abdomen. The pain seem to come in waves that subside after about ten minutes. I am now bleeding more than before the laxative and, at times, it is only blood.
