I just had a bowel movement and afterwards when I wiped there was blood on the tissue.I wiped about six times but blood appeared only ONCE and the second time I wiped NOT ONE SPECK of blood was on there.It was kind of weird.It kind of hurt my anus hole when I had the bowel movement.It felt like it was being stretched.I'm not on my period.What could it be? I'm really scared.

I'm 16 years old.I'm not an elderly person or anything....
