I think jaidoretta's comment is a bit too optimistic about fertility-awareness methods.

The CDC has an information sheet about the effectiveness of different methods of contraception[1] which cite on the order of 18 pregnancies a year for these methods. Interestingly, newer fertility-awareness methods appear to be more effective than this estimate[2].

The effectiveness of the sympto-thermal method (STM), like other methods, obviously depends on a number of factors. One of the big problems is that fertility awareness-based methods are a whole category of methods, which also includes the rhythm method and others that are much less effective that STM.
