Understanding natural fertility, infertility, and related moral and social issues.

Choosing a Method of Natural Family Planning


Coming up soon, I will go into detail about the different methods of NFP, but let’s start with an overview of methods:

Sympto-Thermal Methods are based on a number of signs, including a woman’s basal temperature, cervical mucus, and cervical position.  This method relies heavily on taking your temperature each day at the same time, and typically uses the other signs as supporting information.

Ovulation Methods are based solely on each day’s cervical mucus.  Making these observations regularly and accurately are critical to the success of this category of NFP.

Other Options Include:

  • Calendar Based Methods – This would be the rhythm method, or something similar, where ovulation is predicted based on past cycle lengths.  The two main detriments of the system are that, often, more days of abstinence are required and because most women will have a cycle sometime that is out of her normal range, there is a lower effectiveness rate than with more current methods.
  • Eco-logical Breastfeeding – This is total breast-feeding, where the mother feeds regularly, directly from the breast.  This essentially requires the mother to have her baby at her side at all times.  Obviously, a baby is required for this one to work!

  1. Great post! I’ve blogged a little about NFP but I love that this is an entire blog about the subject, great resources!

  2. I love the picture you chose (edited) for this post! I am still getting to the point of really appreciating the wide variety of NFP methods out there. For so long I was really critical of cycle beads because I felt like it was stupid to not take biological signs of fertility into account. But now I realize that some people are busy, and quite happy to accept the higher chance of an “unintended” pregnancy.
