bewildered parasite cleanser's question

i finished Dr clark's parasite cleanse 2 weeks ago and now i'm on the maintenance program. the only thing i have seen in the stools are white "rice grains" which are still comming out. they must be some kind of larvae, but of what (ascaris? tape worm? other?) how long should this go on? i still get plenty of gas so i assume i'm not cleansed. should i restart the protocol for another two weeks? or do another type of cleanse? i welcome your insights and sugestions.
