Sep 20, 2011
When you use basal body temperature (BBT) method, you need to track the BBT every day at the same time every morning during your menstrual cycle. At the beginning of the menstrual cycle the basal body temperature is usually low, and then it can be a small drop of temperature followed by sharp rise by 0.4-1.0 degrees. This rise indicates that ovulation has occurred. After that the temperature will stay high for the rest of the cycle and drop before your periods.
You have the highest chances of conceiving 2 to 3 days before ovulation and on a day of ovulation.
