Wow, what a long wait! It's likely hemmorhoids (however it's spelled) as was in my case, but I worried, too. I assume it's red blood. Do you have pain in the rectal area? (I sound like a nosy nurse). That usually goes along with the blood vessel problem. I had a rectal fissure one time, too (in college). That really hurt.
Yeah, watch for the signs of cancer. But would any of them get you a colonoscopy earlier? I hope so!
