Welcome to the forum. Blood in stool is usually a good reason to have your doctor to order a stool test to look for infectious causes to your symptoms (like c diff) and refer you to a gasteroenterologist-specialist doctor for a colonscopy with biopsies. It could be IBD like UC, an infection, or any number of things. It takes a number of tests and eliminating the various conditions with overlapping symptoms.
You're not improving, tell your doctor and see what's next.
