Fertility awareness is a method to plan or avoid a pregnancy by recognising the signs of fertility in your menstrual cycle. This page explains how this method works.
What is fertility awareness?
Fertility awareness is recognising the signs of fertility in a woman’s menstrual cycle. It can be used to:
- understand your own menstrual cycle
- plan a pregnancy
- avoid a pregnancy.
How reliable is it for preventing pregnancy?
The method can be 97% effective for couples who can easily recognise the fertile phase and use the method correctly. This means three out of 100 couples will get pregnant each year.
However, typically 25 out of 100 couples will get pregnant each year. This is because:
- couples have not been taught correctly
- couples do not understand how to use the method
- couples have sexual intercourse during the fertile time
- in some women it is difficult to recognise the signs of fertility.
What do I need to learn?
We strongly recommend you consult an experienced teacher before using fertility awareness as a method of contraception/ārai hapū.
You need to know how to:
- understand your menstrual cycle
- check your cervical mucus
- take your temperature
- recognise other signs of your fertile phase
- use this information to plan or avoid a pregnancy.
You can then use this knowledge and some tools to identify the fertile and infertile phases of your cycle. While you are learning this method it is recommended you do not have sex unless you use a condoms or diaphragm.
Where can I get more information?
