The contraceptive vaginal ring is a small, flexible plastic ring that you insert into your vagina. It releases the hormones oestrogen and progestogen to prevent pregnancy and is a convenient.
How does the ring work?
The ring prevents pregnancy by:
- Stopping ovulation (no egg is released)
- Thickening cervical mucus to block sperm
- Thinning the lining of the womb to reduce the chance of implantation
How effective is it?
- Over 99% effective when used correctly
- Around 91% effective with typical use
How do I use the ring?
- Insert the ring into your vagina, where it sits comfortably and cannot fall out during normal activity
- Leave it in place for 3 weeks
- Remove it for a 1-week break, during which you will usually have your period
- After the break, insert a new ring to continue contraception
Your GP or nurse will explain how to insert and remove the ring safely.
When does it start working?
- If you insert the ring on day 1 of your period → protected immediately
- If inserted at any other time → use additional contraception (e.g., condoms) for 7 days
Advantages of the ring
