By using a special thermometer (called "metabolic" or "basal body") you can estimate the day of ovulation by charting your morning temperature. A woman's temperature is lower prior to ovulation. This creates a biphasic (two phases) temperature chart which shows that ovulation has occurred (please see Serono BBT chart attached).

Using the basal body thermometer, take your temperature each morning immediately upon waking up, before getting out of bed, and before eating or drinking anything. Place the thermometer under your tongue and wait five minutes. Chart your temperature on the daily record. It is best if your temperature is taken approximately the same time each day. Remember to start a new chart when your period begins. Day one is always the first day of menstrual flow.

Knowing when ovulation occurs is important. This information will allow you to coincide intercourse with the time of your optimal fertility.

Please bring your current BBTs with you each time you have an appointment at the office.
