What is the BBT Charting Tool?
Looking for an explanation of our charting tool? Here it is! For step by step directions, read below and also click here. The Pregnancy.org Base Basal Temperature (BBT) Charting Tool is designed to help women pinpoint their ovulation as an aid in determining ovulation as a method of natural birth control. All BBT charting tools rely on a combination of ovulation-induced temperature shift, combined with other physiological signs, to pinpoint ovulation. The Pregnancy.org Charting Tool differs from other charting tools by relying on the core math used to determine ovulation, rather than shortcuts created to reduce charting complexity when charting without the aid of computers. Despite that the Pregnancy.org Charting Tool uses sophisticated mathematical models internally these are largely transparent to the chart user: the computers that run the application do the hard work.
