The Primer is made up of the sections that follow. If you want a good overview of how the Fertility Awareness Method (FAM) works, start with the first section and follow it through to the end. If you do not currently know a lot about the cycle of fertility, you will find the Primer informative and interesting.
If you have not yet done so, it is strongly recommended that you also read Taking Charge of Your Fertility by Toni Weschler, as it covers this information in much more detail (and is a very enjoyable book!).
Each section begins with a brief overview, followed by a detailed discussion of the topic.
