Thanks for providing more information.
Sorry for late reply and inconvenience.
As per your description,possible differential diagnosis causing blood in stool may include Hemorrhoids,Anal fissure,Colon polyp,Inflammatory bowel disease,Gastroenteritis.
As you have associated fever,chills,nausea now so it suggests infection.
Drink plenty of fluids and get Oral rehydration solution.
So you make an appointment with your family doctor for a clinical exam and if required further bloodwork like CBC,ESR,Colonoscopy should be done in your case.
Take OTC Advil in the meantime.
If your fever is high with vomiting then visit ER.
Hope this helps.
