blood clots in my stools

Right im 20 year old female, and recently well since december 07 when i was involved in a car accident i've had bleeding in my stools. Have had 2 different procedures done, including a Barium enema, today i went to the toilet and passed a blood clot the size of  about a 5p piece.

Just lately i've had a lot of pain in my back and round my stomach, its been extreemly sore!!

In my opinion, from your symptoms, you should have both an endoscopy and a colonoscopy to check if there is a significant source of bleeding.

Rectal bleeding is never normal and should be checked out to find the cause.

Good luck
