    1. Increased estrogen increases the level of TBG, decreases free T4 and leads to increased T4 production
    2. Increased estrogen increases the level of TBG, decreasing bound T3
    3. Delivery of thyroid hormone to the fetus decreases available thyroid hormone, leading to increased production
    4. Increased TBG due to decreased bound T4 leads to a spike in estrogen until TBG levels even out
    5. Decreased TBG due to increased delivery of T4 to the fetus leads to increased production of TBG
