First round IS FINISHIED, STILL THE SYMTOMS ARE EXIST

Dears,
I've finished taking parastroy for one month, during this round, I have seen in my stool died hookworm several times. once I finsished the first cycle, i examined my stool and the LAB showed that I have still hookworm and CYST and initially I though that I have only giardia lamblia. How ever, the first round of 30 days is finished and I stoped before 12 days ago,so I'm still feeling the symptoms of parasite in my stomach, like bloating cramping, GAS and etc..., so advise? do I start another round of parasatroy when the break of 30 days is finished? do you recommend any thing else. pls note that I have ultimate cleanse which I didn't use yet.

pls advise

Many thanks
Fahad
