Hmmm. I just read this...

A hormone that develops during pregnancy --human chorionic gonadotropin (hCG) -- rises soon after fertilization, peaks at 10 to 12 weeks of gestation, and then declines. HCG can weakly stimulate the thyroid, resulting in a milder, shorter-term form of hyperthyroidism during pregnancy. This transient subclinical hyperthyroidism is also known as gestational transient thyrotoxicosis -- sometimes abbreviated as GTT. GTT usually resolves during the first trimester of pregnancy, and usually does not involve treatment.

That's interesting. I wonder if all of this is just the "peaking" of my hcg levels.
