What should my temperature be when I check it?

You want it to be consistently above 97.8 degrees Fahrenheit, and preferably closer to 98.6 Fahrenheit.

Anything less than 97.8 Fahrenheit suggests low metabolic rate and hypothyroidism.

You'll want to continue checking your temperature regularly, especially once you start taking the iodine and selenium, as you'll likely find that it increases over time.
