What is a vaginal ring?
Vaginal rings are sold under the brand name NuvaRing® in Australia.
They are soft plastic rings that contain 2 hormones – oestrogen and progestogen. These are similar to hormones that are produced by the ovaries and used in
‘the ‘pill’ (combined pill)
.
Effectiveness of vaginal rings
If used correctly a vaginal ring is at least 99% effective at preventing
pregnancy
.
If you forget to put a new ring in, use it incorrectly or take certain medications, it might only be 93% effective.
How to use a vaginal ring
To use a vaginal ring, you squeeze the ring and insert it into your vagina (like inserting a tampon). It stays in your vagina for 3 weeks.
You then take it out and throw it away and wait 7 days before inserting a new ring.
You will usually have your
period
(bleeding from your vagina) a few days after removing the ring. You can skip your period by inserting a new ring straight away and missing the 7-day break.
Most people who use a vaginal ring cannot feel the ring once it is in their vagina.
What stops a vaginal ring from working
A vaginal ring may not work if:
you insert a new ring more than 24 hours late
you leave the ring out of your vagina for more than 24 hours, during the 3 weeks of use
you are taking some medications or natural remedies (check with your doctor, nurse or pharmacist).
How a vaginal ring works
A vaginal ring works by stopping your ovaries from releasing an egg each month.
It also thickens the fluid around the cervix (opening to the uterus or womb). This helps to prevent the sperm from entering.
When you start using a vaginal ring for the first time, or after a break, it can take up to 7 days to start working.
Speak with a doctor, nurse or pharmacist about the best way to get started.
Where to get vaginal rings
Your doctor can provide a script for a vaginal ring which you can take to the pharmacy.
You can only get up to 4 vaginal rings at a time.
It is more expensive than some brands of the pill.

Using a vaginal ring after having a baby

, do not use a vaginal ring until your baby is 6 weeks old as it may reduce your supply of breast milk and may increase your risk of thrombosis.
After 6 weeks you can use a vaginal ring, but other types of contraception might be better choices.
If you are not breastfeeding, you can usually start using a vaginal ring once your baby is 3 to 6 weeks old (check with your doctor, nurse or pharmacist).
