Bright red glue-like substance in my pants out of nowhere. Should I be worried?

Don'tGetStuckToChair. Hell yes! Check your bottom for blood and see what orifice it might have come from. If you can't find out then check your pockets for a burst pen or magic marker or can of red shoe polish. If it never happens again, thank God. And if it does, go see a doctor, even if you don't have any symptoms.Check the toilet and toilet paper every day, too.Best to put a tampon in too to see if that's the source.
