Discharge

Sometimes I get this discharge that is dark brown and the consistency of poop. It isn't poop I know that for a fact 100%. But what is it? My gyno told me once that it could be old blood, but I've seen old blood and it doesn't look like that. It isn't slimy or liquidy like most discharge. It is thick and literally looks like poop. Sorry for the gross description. Does anyone else have this problem or know what this is?
