Unusual: Tarry stool is not a feature of celiac disease but often a sign of gastrointestinal bleeding. You need to see your doctor very very soon.

No: This is not a typical symptom of celiac disease. More common would be diarrhea, loose, watery stools, and failure to gain weight. Tarry stools is a symptom of intestinal bleeding.
