I have heard that you can use a natural way of not getting pregnant (I think it is called natural family planning) how does this work?

The Fertility Awareness method (sometimes called natural family planning or the rhythm method) works if you don’t have unprotected intercourse during the most fertile time of the woman’s menstrual cycle. This form of contraception involves checking your temperature and your vaginal secretions daily. You need to learn this method from an experienced teacher and track your cycle for several months.

For this method to be effective you need advice from Natural Fertility (check in the phone book), a doctor or a nurse.
