- The ring is a form of combined contraception containing oestrogen and progestogen. It mainly prevents ovulation and makes the mucus at the opening of the womb harder for sperm to pass through.
- Wear the ring according to a fixed schedule and replace it on time. A regular routine matters because mistakes reduce its reliability more quickly than many people think.
- The ring does not protect against HIV, gonorrhoea, chlamydia or other STIs. If you are at risk of an STI, you also need barrier protection.
- Combined contraception slightly increases the risk of a blood clot in a vein. For most healthy young users this extra risk remains small, but it matters more if you have personal risk factors.
- Always take your medical history, migraine pattern, smoking, blood pressure and medicines into account when choosing a ring.
