Your symptoms are suggestive of intestinal infection. You may need a course of antibiotics as bleeding usually denote a bacterial infection.
The initial management is as following;
1) Pepto Bismol
2) Lomotil; may only be given if the diarrhea is vigorous.
3) Gatorade / Pedialyte
4) Plenty of fluids
5) BRAT diet; banana, rice, applesauce, toast. Vegetable broths / vegetable soups, coconut water also can help.
7) A tablespoon of apple cider vinegar in a glass of water twice a day.
Dietary measures would help you in regulating the bowels. Vegetables and fruits will help. Probiotics and probiotic yogurt are recommended. You may drink diluted fruit juice, Pedialyte or Gatorade.
Eating foods that are higher in soluble fiber (introducing slowly dried beans, oats, oat bran, rice bran, barley, citrus fruits, apples, strawberries, peas, and potatoes).may aid in making stool firmer. A bland 'BRAT' diet including bananas, toast, oatmeal, white rice, applesauce, and soup/broth may improve symptoms.
Probiotic supplementation has been shown to reduce the severity and duration of bowel issues.
Diverticulitis may be the other possibility of the diagnosis. That too may need the same treatment.
