It took a while before anything happened to my periods ; but after I upped Iodine to over 50 mg a day, my periods slowed down a bit; from 24 days apart getting close to 28 again, and from one HEAVY day(stay at home-like day)
to more light period as before I got thyroid issues.
I have not had this heavy first day since last summer; from when I upped the dose. Clotting is less; but not gone completely. Now when the FBD is gone (more or less)it is not easy to say when the period is coming, so I just have to count days.
