I think adrenal problems can also lower temperature. Or you might just have circulation problems which don't seem to affect BO working. You can't just take BO when your temperature is high, though. You need to take it regularly for it to work. If your thyroid is fine, I think you should be fine since that is what the temperature is supposed to measure. If you're really concerned, try some thermogenics like ginger tea.
