i think four drops daily is fine. this is the critical time for the deveoping baby to have Iodine available. it is good that you were supplementing before getting pregnant. the summer cold is the mucus building up again. if you were doing fine with four drops, thats what you should do. it shouldnt be enough to cause any kind of detox that might effect your progress. hopefully you dont have any Amalgams in your mouth. avoid vaccinations after birth and the child will surely avoid a multitude of possible problems, most notably autism.
