I had diarrhea last night that progressed to it having pebble like poop and diarrhea. then i had small amounts of blood in the feces and sometimes i would just poop mucuous with blood . it has subsided but should i get a colonoscopy or something?

If you're eating out before that event, chance is you have an infectious bowel disease which manifests with diarrhea, mucous and bloody stool. Problem is usually limited without treatment but at times it may be treated with antibiotic(s), less likely if you live in the USA. I think colonoscopy is NOT indicated for these symptoms. However, you should see your doctor if symptoms persist. Take care.
