Fertility awareness-based methods of pregnancy prevention. Accessed Jan. Frequently asked questions. Contraception FAQ Fertility awareness-based methods of family planning. American College of Obstetricians and Gynecologists. Fowler GC, et al. Natural family planning methods can work to prevent pregnancy for some women.
However, there are many limitations to these methods, making them less effective than most other hormonal and non-hormonal contraceptive options. NFP methods are time-intensive and require significant commitment from both the woman and her partner. Women are advised to track their cycles for at least 6 cycles to learn about their cycle length and signs of fertility before relying on this method to prevent pregnancy, leaving them vulnerable to unintended pregnancy if no other contraceptive method is used during this initial period.
Women must also pay attention to signs of fertility such as vaginal discharge and temperature daily or multiple times a day, and correctly interpret their observations. Finally, the woman must be able to remain abstinent during the fertile window, which can last up to 12 days a month depending on the method, or use a barrier method. Many women may not be good candidates for the use of NFP including women with multiple sexual partners and women with irregular cycles Text Box 1.
Some methods, such as the calendar-based methods will not work for women with cycles shorter than 26 days or longer than 32 days.
In addition, cycles and signs of fertility may vary for each woman, and even from month to month, due to a wide range of reasons including stress, sickness, sleep deprivation, use of certain medications and alcohol, making these methods less reliable. Finally, these methods do not protect again sexually transmitted infections. Natural family planning methods require varying levels of training and technology to use correctly.
For calendar-based methods, women may use a physical calendar or CycleBeads to track the days of their menstrual cycle. However, most methods now have mobile apps, including iCycleBeads.
Some apps simply make it easier for women to log their biological fertility markers online. Mobile health apps that are not considered medical devices do not require FDA approval for promotion and use in the United States. No mobile health app has been approved by the FDA as a contraceptive device. One app, Natural Cycles, was certified in the EU as a contraceptive device in , the first app to gain government approval.
Recently, Natural Cycles has come under scrutiny. Less than a year after its certification by the EU health agency, a Swedish hospital reported that 37 out of women seeking abortions there between September and December had used Natural Cycles as their primary contraceptive method.
FABMs that track multiple signs of fertility sometimes require training with a licensed provider. There are organizations, many of them religiously-affiliated, dedicated to teaching and promoting these methods of natural family planning, such as the Couple to Couple League. Some of these groups have also developed their own model of natural family planning, such as the Creighton Model Fertilitycare System CrMS , Sensiplan, and the Marquette Model, although these brands still rely on some variation or combination of temperature, cervical mucus, hormone, and cervical position tracking.
FABMs are generally inexpensive to use. However, there are exceptions. These instructional classes are not often covered by private insurance plans or Medicaid. However, it is unclear whether plans would cover branded classes such as the Creighton Model Fertilitycare System. This means that 1 to 9 women in who use natural family planning correctly will get pregnant. But if natural family planning methods are not quite followed correctly, more women will get pregnant.
It takes commitment and practice to use natural family planning effectively. Most women can use natural family planning. However, certain situations can affect fertility signs and you might want to consider a different method if:.
