black thread looking worms in stool

can anyone tell me what kind of parasite this is ? i did my 4th liver cleanse last night and this morning there were hundreds of black threads in stool. they were thin strands like human hair but in pieces no longer than one quarter to a half inch long. i cant find my cure for all disease book but i remember seeing a photo in that book of some kind of fluke in a toilet that looked just like what i purged. anyone seen this or know what it might be....is this whats responsible for the wigglies i've been having ?
