Also the doctor said my body was fighting it so she's happy about that I have over active thyroid
"Antithyroid drugs are the main therapy for maternal hyperthyroidism. Both methimazole (MMI) and propylthiouracil (PTU) may be used during pregnancy; however, PTU is preferred in the first trimester and should be replaced by MMI after this trimester. Choanal and esophageal atresia of fetus in MMI-treated and maternal hepatotoxicity in PTU-treated pregnancies are of utmost concern. Maintaining free thyroxine concentration in the upper one-third of each trimester-specific reference interval denotes success of therapy. MMI is the mainstay of the treatment of post partum hyperthyroidism, in particular during lactation."

IIRC about 30% of women have thyroid enlargement during pregnancy.
The levels can get normal after delivery, and there is a 50% chance thyroid size will get to normal as well.
How about blood flow within the thyroid? any numbers representing the measurements?
