The number of women in England and Wales who are turning to less reliable fertility awareness methods of contraception rather than dependable hormonal options before having an abortion is increasing, according to research in BMJ Sexual & Reproductive Health.
The decline of hormonal contraceptive use in favour of natural, tracked methods has made raising awareness of what is at stake more urgent as less effective contraceptive use is linked to unintended pregnancies.
Fertility awareness methods' failure rates range from 2% to 23%, whereas hormonal methods' rates are as low as 1%.
This shift is being attributed to a preference for 'natural' methods, which are increasingly promoted via social media.
From 2018 to 2023, the percentage of women requesting abortions in the UK who used fertility awareness-based methods rose from 0.4% to 2.5%, but hormonal contraceptive use fell from nearly 19% to just over 11%.
There was a significant decline in the use of long-acting reversible contraceptives, such as implants.
The percentage of women who reported not using any form of contraception at the time of conception increased by 14%, from 56% in 2018 to almost 70% in 2023.
Finally, Comprehensive awareness campaigns can help ensure that women can make informed choices, ultimately reducing the potential for unintended pregnancies.
