Thanks for providing more information.
Well as you have blood in stool and diarrhea so it suggests possible causes like Gastroenteritis,Intestinal parasitic infection,colitis,Inflammatory bowel disease.
And it shouldn't be ignored so i suggest you to consult your regular doctor for a clinical examination and undergo further blood work like CBC,ESR,stool routine examination,colonoscopy for further evaluation.
Blood in stool can also be caused due to anal fissure,Hemorrhoids so an ano-rectal examination should be done in your case.
A referral to gastroenterologist should be considered in your case.
If you are unable to contact your doctor today or tommorrow then you should visit ER.
I hope this helps.
