pinworms / other parasites

My daughters and I have just been treated for pinworms. I do follow the Dr. Clark protocol for years and have read all her books. That's why I was horrified we got pinworms in the first place. I did opt to have us take the prescription drug - Mebendazole - in addition to treating with the Dr. Clark stuff. Last night after taking the RX, in my bowel movement, I saw several white worms that looked like pinworms that were MOVING and many tiny little black specks that were SWARMING around the 2 pinworms. ugh! The black specks were tiny and moving very quickly and literally crawling halfway up the toilet, sliding down, then back up again. I am wondering if anyone has any idea what these are? Are they the pinworms before maturing or the eggs or a totally separate parasite? The doctor stated that the Rx should kill all the worms, but I am still feeling the creepy crawly moving sensation around the anus today all day, so I know something is still alive there. I am disgusted and horrified. I have taken the Black-Walnut hull, cloves and Wormwood today plus going to zap right now. I have done a liver cleanse as recently as 3 weeks ago. HELP!! Should I do an enema with Black-Walnut hull tincture? Any thoughts on additional treatment for my children - ages 8 & 4? Any advice or insight would be appreciated.
