Interesting about the ferratin...that has been my obstacle although the benefits are huge with iodine. My last period was 1 week late and no clots and no cramping (actually a first in terms of the NONE). It was getting better each month but this one was the best I ever had. I think that will help with the ferratin as I don't think I lost much. I am eating all iron rich foods and take black strap molasses to boost the ferratin. Low iron seems to go hand in hand with all these thyroid issues......
