Natural family planning is a method which involves assessing when a woman is most fertile during her monthly cycle and avoiding unprotected sex during this time.

It requires a woman to plot the times of the month when she is fertile and when she is not.  You also have to record fertility signals such as body temperature and cervical secretions (fluids or mucus) to identify when it’s safer to have sex.

Fertility awareness should only be used if you have been taught by a specialist teacher.
