If : If you have very strong-smelling stool, and if it's very dark in color, you may be having melena. Melena is clasically described as "black, tarry stool, " and is caused by bleeding into the upper part of the intestinal tract. It doesn't look like blood because it's been digested. If this is what's going on, you should be seen by a doctor and evaluated as soon as possible. Bleeding like this can be dangerous. Even if this doesn't sound right, a change in stool is still worth discussing with your doctor.
