Is it rectal or colon cancer?

Ho doctors, I am dying daily i fear or cancer. All started in last year feb 2022 when i started gettting ibs symtoms. I met gastrointestinal doctor, and she prescribed me some medicine for one month. Issue got resolved after that but fear of colon cancer setup in mind. I started going loo and try to forcefull motion to see if blood is comin or not.. Unfortunate, in july 2022, i saw first blood incidents. I did two stool test after that and all came neagtive. But from there onwards, i was taking stool in hand and checking for blood. I started seeing blood incident after every 15 16 days gap. It comes suddenly and thenstop for many days. Intially, there was slightly burning sensation when blood used to come. This continued till yesterday. Yesterday, i fear for cancer, i went 8 time motion even there was no urge and now i am seeing very little blood at start of first stool cominh out or anus. having burning sensation after motion.there is no weight loss in last 8 month.suggestplz
