You can't always see parasites. A lot of them hide inside your stool, so unless you are really looking and maybe even doing a bit of investigating you won't always notice them. What you will notice is your health improving little by little(it won't be over night)
When my sister started cleansing because I asked her to, she isn't in bad health, she didn't think she had parasites because she wasn't seeing any in her stools, maybe a few eggs, she continued to cleanse to please me, and the second week she had many flukes show up and a 1 1/2inch Ascaris came out of her nose when she blew it(dead),she does have some sinus problems. So she wanted to continue the cleanse after that, and now it has been around 2 months and she has had some that are 5 and 6 inches, some Ascaris and tan worms, she can't thank me enough now, which I don't want, I just want everyone to become as healthy as they can. My sister now has her husband and 4 children cleansing.
I didn't see the larger ones for about a month into the cleanse, I feel they are more resistant to the herbs. I am still getting large ones out, this morning a 7", 4" and 2" Ascaris came out. I was VERY heavly infested with parasites for years(I know this now, not then). I celebrate everytime I get some of the larger ones out, that is sooo many less eggs in me each day that I won't have to fight to kill.
I have really been blessed, I had to figure out with lots of prayers and the Lords guidance what was wrong with me and what to do about it. You have been blessed also, somehow you ended up here learning about parasites and the bad health they cause.
I hope that you don't quit cleansing too soon, I would at least do a 3 to 6 month cleanse (or longer if your health is not better), give the larger ones a run for there lives!!!! heyjude
