Changes in body temperature during ovulation are caused by fluctuations in progesterone levels, reports Parenting.com. Progesterone levels are lowered prior to ovulation resulting in lowered basal temperatures. 12 to 24 hours after ovulation, progesterone levels rise and raise the body temperature. In addition, the bump in progesterone thickens the uterine lining to prepare for a possible pregnancy. Using this method of fertility tracking when trying to conceive is not the most efficient. Conception is most likely two days before ovulation up until the day of ovulation, while monitoring body temperature will give 12 hours' notice at best. In addition, a special thermometer is required to record temperatures with appropriate precision, and false readings are common occurrences despite this.

Other options for fertility tracking include the Billing's method and hormone tracking, adds WebMD. Immediately prior to ovulation, cervical mucus is clear, stringy and found in higher quantities. Hormone tests use urine to detect levels of luteinizing hormone. Combining all these tracking methods and examining the body for symptoms of ovulation provides the best method of fertility tracking.
