Fertility awareness works by observing and recording your body’s different natural signs each day of your monthly cycle. The main signs are:
Changes in these fertility indicators can help you to identify your fertile time. You can also use fertility monitoring devices which you can buy in a chemist.
A specialist teacher will show you how to record the signs and explain what you can tell from them.
Fertility awareness doesn’t mean ‘withdrawal’ (removing the penis before the man comes).
A menstrual cycle, on average is approximately 28 days (although this can be longer or shorter) and the fertile period lasts for around eight to nine days.
This is because eggs can live for 24 hours (and there can sometimes be a second egg released after 24 hours) and sperm can also live inside the body for up to seven days, so if you had sex seven days before ovulation you may still become pregnant.
Fertility awareness must be properly taught. Then the instructions must be properly followed or it will be much less effective.
Recent use of hormonal contraception may affect fertility indicators until regular menstrual cycles have been established. Women should have a minimum of three complete cycles after stopping hormonal contraception.
Other medication, for example pain relief, antihistamines and some antibiotics can also affect different fertility indicators.
Most women can use this method if they have sufficient commitment and can share the responsibility with their partner.
However for some women for whom pregnancy poses a significant risk relying on fertility indicators for the prevention of pregnancy is not recommended.
There are phone apps and online systems however the reliability and effectiveness of using these is not known, you should always be taught fertility awareness methods by a specialist teacher.
