basal body temperature (BBT)

Charting your basal body temperature (BBT) is an important step in tracking your fertility when trying to conceive. Charting your BBT involves taking your temperature with a basal body thermometer (which measures precise changes to one-tenth of a degree) at the same time each day beginning on the first day of your period. You can use the babyMed BBT Chart in order to track these temperature changes and learn how to interpret them.
