Blood in the stool is usually indicative of parasites (worms) or coccidia. You need to take a fresh stool sample into the vet on Monday so they can get this treated. If you are certain the blood is in the stool and not in the urine you can safely wait until the vet opens on Monday to have this diagnosed. If the blood is in the urine, this is more serious and may need vet assistance over the weekend. Please let me know if I can assist further!
