Temperature Question

Hello, everyone.

I understand that (thorough) blood work is the way to go, and I'm going to obtain that from a lab in the very near future, but for the moment I have a question about body temperature.

My temperature first thing in the morning can be very low - around 35.3C/95.54F - but throughout the afternoon and evening I hover around the 37C/98.6F mark. In matters of the thyroid, is it the basal temperature that tells us the most? I do feel like death, and tick a fair few boxes on the thyroid front, but for a fair chunk of the day, my temperature is more or less perfect.
