I'm 19 and pretty healthy. Yesterday I woke up and got my period. When I had my BM in the afternoon, I was shocked to see a little tiny tiny (only visible if you look really closely) streak of red on the surface of the tip of the stool which I'm not even sure if it's blood but it looked like it was painted on the stool. It's really small like less than 1cm. Everything else was pretty much chocolate brown. Being the hypochondriac that I am, I can't get it off my mind. Any idea what this is? Maybe just my period? I'm really scared of colon cancer..
