Rectal Bleeding on and off for two years

ive had rectal bleeding for the past two years and it’s been on and off. No swelling, no pain. It’s bright red blood that sometimes is in my stool, drips down into the toilet bowl, and is enough to turn the toilet water red. My stool is normal, with no weight loss or any other kind of symptom. Sometimes it comes back daily, and some other times there’s just a small bit of blood that isn’t too noticeable both in the toilet bowl or in the toilet paper.

Keep in mind I’m a teen with no serious symptoms or anything. I figure it might be internal hemorrhoids or something like that
