So today in my bowel movement I noticed this red chunk that I thought was food but when I examined it it fell apart and smeared on the toilet paper leaving a bright red (sort of orangey) mark. I'm terrified this is blood. I've also been having more frequent (but still solid) bowel movements, but before now I thought that could have been just because I have been anxious about my bowel movements lately and that was affecting it. I'm scared because this red piece was quite big. The rest of my stool looked normal though. Btw I'm 19.
