Just found out that I have hypothyroidism along with antibodies against the thyroid tissue at 10 weeks of gestation. Iodine is important in early brain development and maternal hypothyroidism has been linked to mental retardation in the offspring. Apparently it is better to be treated as early as possible but I missed the developmental window of the first trimester. Has anyone else been diagnosed between first and second trimester and being treated? I would appreciate heating your experience as I am frantically trying to find an endocrinologist to treat me.
