Basal body temperature (BBT) is your morning body temperature before you get out of bed.
It’s important to check your temperature every day using the Basal Body Temperature chart. Your basal body temperature chart is a big tool in your treatment. Please bring your temperature charts to every appointment.
- Place thermometer under your tongue first thing in the morning. Always check your temperature just after you awaken, do not get out of bed, go to the bathroom or drink first.
- You may use any thermometer that includes 97° - 99°, you do not have to buy a special basal body thermometer.
- The first day of the menstrual cycle is the first day you bleed, whether it is 14 days or 90 since your last menstrual flow.
- Always go to the next graph with each new period
- If you go longer than 41 days between bleeds, go on to next graph, then begin a new one when you do bleed.
- Place a dot on the intersection of the cycle day and the temperature.
- Indicate menstrual flow by an “X” on the 98° line.
- Indicate medications taken (Clomiphene etc.), sick days, etc., on notes.
