Basal Body Temperature Chart

Use a basal body thermometer (available at most pharmacies) to take your basal body temperature ( BBT) as soon as you awake in the

morning. Plot your BBT as a dot on the graph for each day in your menstrual cycle. Connect the dots with a line from day to day so

you can see a pattern. The pattern may vary from cycle to cycle, but over time you will begin to see when you tend to ovulate.

After ovulation, you'll see a spike in your temperature ranging between 0.5 and 1.6 degrees. You are most fertile two to three days

before you ovulate and for about 12 to 24 hours after ovulation.
