“The cons of fertility awareness methods are: they don’t protect against STIs, you will need to avoid sex or use another method of contraception during fertile times, and it’s a high level of commitment. If you have an irregular cycle, it can be harder to recognise fertility indicators. If you’ve recently stopped taking hormonal contraception, you’ll need to wait at least 3 hormonal cycles to ensure you’re back to regular cycles,” says a spokesperson from Brook.
“No method of contraception is 100% effective. However, fertility apps carry a greater risk of the user experiencing an unplanned pregnancy than long-acting methods, such as the coil or implant,” adds Tracy.
It takes a while to learn how to track your cervical mucus and body temperature – usually around 3-6 months – and it requires a lot of practice and dedication. As your cycle can vary from month to month, it can be really hard to accurately pinpoint the moment of ovulation.
Getting pregnant accidentally isn’t a deal-breaker for some people, but it may be for others. There is no one glove that fits all when it comes to contraception (that’s why condoms come in so many different sizes!) so you need to find the right method for you.
When done perfectly, fertility tracking can be 99% effective at preventing unplanned pregnancy. It is, however, a lot more hands-on than other contraceptive methods and easier to get wrong, which can greatly reduce its effectiveness. You will also still need to use another method of contraception, like condoms, if you want to have sex during your fertile window.
And as many people who’ve shared their MyMorningAfter stories with us will agree, in the heat of the moment people don’t always reach for a condom.
