Welcome
Welcome to the NFP Charting Online website, a site that allows you to do all of your Billings Method charting online. This utility is based upon the Billings Ovulation Method of Natural Family Planning, and we recommend it not be used by anyone that has not been trained by either a BOMA-USA or a WOOMB Certified teacher.
