The other comment that I was going to make is that I have gained 6 pounds in two days after a week of clean eating and my period has been every 28 days for 5 days like clockwork until this month. I think that it more than likely a reaction to iodine. Maybe I just ramped up too fast. Tomorrow I will go down to 7.5mg and see what happens. if the weight starts to come down then I'll stay there.
