parasites can settle in most any organ of the body. Before my health turned bad in 2010, I had always had a small clot or so during my period, so after I got sick, found my worms, I didn't think much of the clots. One day i realized a clot seemed elongated. I soaked it in water, and it stayed firm, although blood stained. I realized that it was a small worm or a piece of one. I didn't freak, cause it went away when I got rid of them, just figuring that one lost it's way attracted to the blood.
Clear you body of the parsites, and your issues, even the endometriosis might be cleared up.
