Worried I have bowel cancer.

Hi, I'm a 22 year old female with 2 children. For the past 2 weeks I've been having blood on my stools and when I wipe, I am so so anxious and scared its cancer. My partner has the day off tomorrow so I'm going to brave it and make an appointment with the doctor. I dont really have any other symptoms apart from my bum feels very sore. I also have a skin tag on my anus sorry TMI so it's hard for me to feel for anything. No real purpose to this, I'm just so worried, I have really bad health anxiety and it's making me so scared
