Yeah.. pretty 'normal'.
It's probably bleeding from the fact that you've wiped that area repeatedly causing the skin to be irritated, and eventually broken. That's where you're most likely bleeding from.
Nothing to panic about, just be gentle. Perhaps use some wet wipes instead of normal toilet paper?
Unfortunately it will most likely scab, so if you're not careful again tomorrow it will start to bleed again.
No need to panic and run off to the doctor but try to get you diarrhea sorted out and don't wipe too hard.
Don't worry, it happens to the best of us.
