It seems to me I heard that those stones don't necessarily show up in ultrasound, but I could be wrong. Anyway, they can also be in the liver, by the zillions. People with no gall bladders have expelled tons of the stones. If it were me I would do 1-3 liver flushes, after a month of parasite cleansing. If you see stones, continue, if not, you did yourself no harm really.
I preferred not to use Epsom Salts or lemon juice, used orange juice & it worked just as well. If you decide to do it, best to do on a weekend of course. A good time to relax & take it easy. Sipping on about 2-3 tbsp. of apple cider vinegar in a quart of water all day will really make more of them show up. Be sure to taker some potassium (Twinlab has worked by far the best for me) and/or eat some bananas afterwards and eat acidophilus yogurt.
