PNF is based on a woman's knowledge of fertility. You'll learn to recognize certain fertility signs that indicate whether you're in the part of your cycle that's fertile or not fertile. You'll also learn how to make your observations and annotations, using a mobile app. With the Sump-to-Couple League (LPP) Symptomothermic Method it takes only one minute each morning to take your temperature when waking up and a few moments during the day for other observations. Once the information is written on your mobile phone, you will have a complete picture of your fertility... it's that easy!
Now you can have a natural way to space or achieve a pregnancy... a modern method of natural family planning (PNF) that has proven to be 99 effective in postponing a pregnancy... also used successfully by couples looking to conceive.
