Hi, my name is Tim...I'm 17yrs old. Since middle school, I've had bloop in my poop, but it wasn't a significant amount so I made nothing of it. This morning while sitting on the toilet, when I released gas I guess, nothing but blood came out, the most that I've ever had. I don't feel any pain though, what should I do? I'm worried because I don't know if it's cancerous or something, I need answers.
