WOW what a testimony!
I think that some of the reasons for your success is all the companions you are taking; too many jump over this part when they start iodine. I also simply love that you had the courage to go as high as 200 mg and that you did it because you felt it was needed. Way to go!
Your heavy clotting periods is a typical hypo symptom; I believe it will take some time before it gets better, but it will.
Your discharge; I would not worry as long as it is clear and without smell or discomfort. I had something similar years back when I had yeast infections; It would end with a clear discharge; I then knew that the infection was over, like a kind of cleansing.
