Natural Family Planning

The idea behind natural family planning is very simple. A woman is fertile for only about 100 to 120 hours during a month. Let's call this time period the "window of fertility." By avoiding sexual intimacy during the window of fertility, pregnancy can be avoided. This method can also help achieve pregnancy by understanding the fertility cycle better and learning when the probability of conceiving is highest. The question that various natural family planning methods are trying to answer is "How do I determine exactly when the window of fertility starts and ends?" If the window could be determined with 100% accuracy, then natural family planning would be a nearly perfect birth control method. However, the window can only be estimated (estimated though with high probability). To determine the window of fertility, these methods use such things as temperature, mucus, and cervical changes.
