First of all I would like to comment on your TSH. It is a useless waste of time to determine your thyroid health. Doctors like it because it is patented and makes money every time it is used ( is this a surprise?)
The TRUTH about TSH is here: http://www.stopthethyroidmadness.com/tsh-why-its-useless/
Metabolism is the MAIN function of your thyroid. Here is what counts most of all: Your body temperature (Metabolism). Is it lower than 98.6 degrees? Do you feel chilly, cold hands & cold feet? then you are hypothyroid. PERIOD and I don't care what your doctors say. http://www.stopthethyroidmadness.com/temperature/
PS) There are some special rules for women to get an accurate temp reading. Certain days of the month provide a more accurate reading related to ovulation, otherwise temp my be 98.3 degrees at other times. Google "Temperature reading for women" Hormonal birth control can also affect temp. I don't have a good document reference yet for this subject. If you find a good link, please let me know.
