Anyone know anything about iodine levels during pregnancy?  I just read about how important this mineral is and I have no idea if I get enough of it.  I know it's found in salt but I try not to over do sodium and I'm not a big seafood person (also found in fish/seaweed).  How common is this deficiency actually?  Or is it rare that I would be deficient?  My doctor did not say anything about it at my first appointment and it's not in prenatal vitamins even though it is supposedly so important for fetal brain development in the first trimester, which is just about over for me.
