Im sorry for your miscarriage but you need to be looking way beyond just Iodine for an infection. A miscarriage is a very clear and loud sign from your body that its in no way, shape or form capable of supporting a growing fetus. If you value your own health and that of a newborn child you should undergo an extensive supplementation protocol for about a year before trying to have another child. Your clearly deficient in multiple nutrients and if you ignore that you risk having another miscarriage or bring a child into the world with birth defects.
