Copper IUD
The copper IUD is a small device placed inside the uterus that prevents pregnancy through the release of copper ions. It's over 99% effective and lasts up to 10 years. Because it contains no hormones, it doesn't cause hormonal side effects.
It can make periods heavier and more crampy for some women, so it may not suit those who already have heavy, painful periods. It requires an in-person insertion procedure.
Barrier methods and natural approaches
Condoms are the only method that also protect against STIs. They're available without a prescription and are about 98% effective when used correctly. Diaphragms are another barrier option, though they require fitting and are less effective than condoms.
Fertility awareness methods — tracking your cycle and avoiding sex on fertile days — are hormone-free but require commitment and are less reliable than other methods. Your GP can discuss whether this approach is suitable for your situation.
Which option is right for you?
The best non-hormonal option depends on your lifestyle, how effective you need it to be, whether you want a long-acting method, and whether you also need STI protection.
Your GP can talk through all the options, help you compare effectiveness, and arrange the method that suits you best — including referrals for IUD insertion.
