I have had been experiencing blood in my stools lately. This started about two months ago and occurs about twice a week. My stools are not painful, but the sensation that I have when I need to go to the restroom is extremely sudden, and I have to drop everything and go to the restroom as soon as possible. Sometimes it's a small amount of blood on the toilet paper, but others there is a LOT of blood in the toilet and on the paper. I am a twentyone-year-old female with no prior medical history. I started taking fiber capsules about a month ago, thinking that the blood would stop, but it hasn't.
