Well I finally got the other result from my nurse and she said the one that matters (FT4) is normal but TSH is still low. She said it's fine and they would just recheck in 3 months. But she said if I am nervous they would refer me to an endocrinologist. I went ahead and made an appointment with one for next Monday. I figure it doesn't hurt to be extra careful. Even though I am pretty sure its nothing worrysome.
I did a little research and it looks like high levels of hcg can sometimes mimic the actions of TSH. Therefore the body down regulates the TSH and makes it go lower, but the hormones that do the actual work, T3 and T4, stay normal. So it looks like I am okay for now!
In other news my mom will be here tomorrow through the weekend and it is shopping time.
