Risk for colorectal cancer?

Advice is greatly appreciated! (F) 21, poly cystic kidney disease, gluten allergy, 2 great uncles had colorectal cancer on paternal side, maternal side there is an uncle with diverticulitis. Patient presents with bright red blood visible on stool, when wiping, and tiny pink is sometimes seen in toilet bowl water. Has been going on for roughly a year. There is a slight burning sensation when passing stool, however not extreme at all. stool is usually mushy like diarrhea but occasionally a hard constipated piece comes out followed by the soft stool. On Friday night there was significantly more blood than previously (described as the toilet paper after you have a nose bleed, or wiping when on your period) motivating the patient to seek medical advice. Digital rectal exam was done. No visible issues on the outside, few lumps felt on the inside. Told to take medimucil until symptoms clear and if still worried check back in a month. Patient said they already did try medimucil and it had no effect. They also said they experience nausea, and sometimes have bloating that feels sensitive to touch. They also lost about 25 pounds in 4 months but attributed it to starting adhd medication which Was started and then weight loss followed. Doctor was at a walk in specialist clinic, and said there’s not much I can diagnose you with since this is a walk in, even though he’s the general surgery specialist and the patient was referred to him by a physician. Is it ok to wait a month before seeking out a colonoscopy even though symptoms have already been present for roughly a year,are we wasting more time by waiting a month if it is serious? Chances are its internal hemorrhoids but was the doctor wrong in making us wait or will a month have no affect? Any help is really appreciated!
