What is temperature charting for?
More about this last point: A biphasic curve has two phases: before and after ovulation. Charting not only helps you plot the biphasic curve, but you can measure the length of the two phases as well. If the second phase is too short (less than 12 days), this can cause problems with implantation of fertilized eggs. Fertility charting can help reveal such an issue.
