I can only go by what the doctors say when taking the temp on what to add or subtract, though when I say by mouth, I'm talking basal temp, which requires you to take it for 10 minutes to get the true results. When going to any type of fertility doctor this is the method they will have you use in order to get your BBT to watch your cycles. The basal temp is also the temp you are looking for when doing nbe because it not only tells you what your body is doing with your cycles, but also what your metabolism and thyroid are doing.

So basically you can take your temp with the regular digitals, but 10 seconds isn't going to give you a true reading. They do make digitals that will keep taking the temp as long as you want. Luckily they are usually the really cheap ones, since they don't have an alarm or such to tell you when the reading is done.
