Ok I know this is disgusting but I've been researching and other people have been having the same problem! I keep finding what looks like poop in my pants! I've had it for like 3/4 days now and I don't know what to do. People say your starting your period (i havent started yet) but I have no cramps or pains, what do I do? I'm 15 and and do clean down there properly! Honest!
If it's reddish brown then it's the start of your period. If not then diorrhea or your anus muscles aren't working properly and are letting poop out into your panties. That's all I can think of.
