Obtain a referral to a gastroenterology physician for a diagnosis and treatment of what may be a "irritable bowel" syndrome, or even hemorrhoids which can cause intermittent bleeding.

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor, preferably a gastroenterologist. Wish you good health!
