How to Record Your Basal Body Temperature (BBT)
- Before taking your temperature, a minimum of 3 hours consecutive sleep must have been had.
- If you use a glass thermometer, shake it down the day before.
- Take your daily temperature straight away when you wake up (before any other activity such as going to the bathroom.)
- Record you temperature soon after it is taken.
- Try to take it at the same time each day, when you wake up (instead of getting up).
- Make dots or cross on the appropriate temperature and connect the dots with straight lines.
- If the temperature falls between two numbers on a glass thermometer, always take the lowest.
- Most digital thermometers keep the temperature on it until the next use.
- Note events such as stress, or illness in the Others row.
- Temperatures taken late should be noted in the time taken row.
