Does someone have/have a reference to a concise explanation of how estrogen and thyroid hormones interact? I'm getting really confused.

Could you please be more specific?

Estrogen increases synthesis of thyroid-binding globulin. Thus, during pregnancy total T4 increased, but it is increased due to bound T4, and free (unbound) T4 is in normal range, so that's why pregnant women don't have symptoms of hyperthyrodism.
