okay this is completely off topic but today (sorry for the graphic details) I had a BM and there was a little bit of what looked like blood in it. The BM was otherwise normal. I'm basically really really scared that I have bowel cancer now because that's like the main symptom. IDK if this has anything to do with it, but it's totally normal for me to have periods of constipation followed by soft stools fairly frequently and I was constipated for most of last week, and this week have been going more than usual which was expected, as I said. Could this have any explanation? I'm only 15 and really really freaking out, please please help...
