- Get an underarm thermometer.
- Shake the thermometer and place in on the nightstand beside your bed.
- As soon as you awake in the morning, reach for the thermometer and take your temperature. If you are using an underarm thermometer, you need to leave it under your arm for a full 10 minutes. Do not get out of bed until the ten minutes have passed. While taking the temperature, move as little as possible.
- Take your temperature and record it every day for 2 weeks.
- With normal thyroid, we expect your temperature to be about 97.8‐98.2. If it is lower than that, we need to talk about your thyroid.
- If you are a menstruating woman, start taking your temperature on day 2 of your period.
