Tracking your basal body temperature

Your basal body temperature is your lowest temperature over the course of a day. You should measure your temperature as soon as you wake up for the most accurate results.

What is the BBT?

Basal body temperature (BBT) is the lowest measured temperature that a person has on any given day. Basal body temperature is measured orally, and should be taken first thing in the morning for the most accurate results possible. Changes in basal body temperature can help indicate an upcoming or past ovulation, as it may often dip right before you ovulate, and spike in the two to three days afterwards.

Why does BBT spike?

Basal body temperature is controlled by the presence of certain hormones, and the spike in particular is caused by the rapid increase of progesterone in the system. Progesterone is released in great quantities by the matured ovarian follicle (now known as the corpus luteum) that formerly held the egg, as it plays a vital component in preparing the uterus for, and maintaining, pregnancy. One of progesterone’s effects is causing a sharp increase in basal body temperature, an elevated state that persists throughout pregnancy, but regresses to normal if an egg is not fertilized during a cycle.
