That is very significantly lower, but check it for a few more days, just to have a good average. If you want to read about temperature testing, here is a good site.

What is considered sig lower? I have been taking my temp all morning and it is averaging 97.3
Doctors are required to give you a copy of your test result, if you ask for them. That's the first step that I would do right away. Hopefully the testing included free T3 and free T4, along with TSH. From your symptoms, it sounds likely that you are hypo t. You can get some further confirmation of this by checking your temperature for several times a day for several days and comparing the average to the optimal level of 98.6. Anything sig. lower, along with your symptoms, I would bet on hypothyroidism. When you get some more info, post it and you can get good advice from the many experienced members of this forum.
