Vaginal ring contraceptive

What is a vaginal ring?

A vaginal ring is a contraceptive ring which sits inside the vagina. It contains two hormones, oestrogen and progestogen and stops ovaries from releasing an egg each month.

The vaginal ring is inserted into the vagina on the first day of a menstrual cycle and stays in place for three weeks in a row and is then removed during the period.

A new ring is inserted on the first day of the next menstrual cycle.

How effective are vaginal rings?

If used correctly a vaginal ring ring is at least 99 per cent 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 per cent effective.

How do I 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 three weeks. You then take it out and throw it away and wait seven 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 seven-day break.

Most women who use a vaginal ring cannot feel the ring once it is in their vagina.

How does a vaginal ring work?

A vaginal ring works by stopping your ovaries from releasing an egg each month.

They also thicken 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 seven days to start working. Speak with a doctor, nurse or pharmacist about the best way to get started.

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 three weeks of use
  • you are taking some medications or natural remedies (check with your doctor, nurse or pharmacist).

Where can I get a vaginal ring?

Your doctor can provide a script which you can take to the pharmacy. You can only get up to four vaginal rings at a time. It is more expensive than some brands of the pill.

What is good about a vaginal ring?

A vaginal ring:

  • can be used to skip your period
  • may make your periods lighter, more regular, and less painful
  • may cause acne to improve
  • may reduce your risk of getting cancer of the uterus (womb) and ovaries
  • can help with symptoms of polycystic ovary syndrome (PCOS) and endometriosis.

Once you stop using a vaginal ring your fertility quickly returns to normal.

Are there any side effects from using a vaginal ring?

  • an increase in vaginal discharge (fluid from the vagina)
  • irregular vaginal bleeding
  • nausea
  • sore or tender breasts
  • headaches
  • bloating
  • changes to your skin

Can a vaginal ring cause any serious health problems?

The vaginal ring slightly increases your risk of a deep vein thrombosis (blood clot), heart attack or stroke. It may also lead to a tiny increase in your risk of breast cancer. The risk of developing breast cancer due to vaginal ring or pill use in people aged under 35 years is 1 in 50,000.
