It is extremely important that you do you own research, figure out your symptoms and problems, and go in armed with that knowledge. never depend on the doctor to look out after your best interest. You have to be your own advocate.
check out that website i posted earlier and start taking your temperature 1st thing am and then several times during the day.
low avg. body temp <98.4 = hypothyroid issues
fluctuating body temps (i.e. 96.5 at 8am, 98 at 11am, 97 at 3pm, etc. OR starting off high 98.4 then dropping quickly during the day) = adrenal/cortisol problems (i.e. - not enough of it)
I just started this myself and learned that I go from 96.2 to 98.8 over the course of the day. Big jumps an hour after I take my cortisol and then my temperature stays around 98.2 to 98.4 until I go to bed.
this doctor has a great website with some helpful information - http://www.drrind.com/therapies/metabolic-temperature-graph
