Hi, I'm 16-year-old female. And this past week I've been having bright red blood in my stool. This never happened to me before. There wasn't any pain and I didn't strain myself. First time when the feces came out, it looked normal, but then second time, it would be covered in bright red blood. I'm not sure if it's hemorrhoids, but is it something I need to be worrying about? Do I need to go see a doctor?
