Great.....Just had my annual bloodwork done with my OB/GYN and my TSH came back low. My sister was treated for Graves about 15 years ago, so there's a family history, although I know that's just one of several potential explanations for a low TSH. My OB has sent my test results to my GP, so I suppose we'll go from there in figuring out what's going on.

I can't say that I have any real symptoms. Lately, I've felt hot a lot of the time, but it is 80-90 degrees outside most of the time. My weight's been pretty steady, I'm not overly tired. I've always been moody, so that's not a great indictator. I should probably take a pregnancy test just to be sure, but my TSH was lower than what's even considered normal during the first trimester of pregnancy.

Anyway, just one more thing to worry about.
