the vaginal ring contraception
If you like it then you better put a ring on (in?) it. The vaginal ring is one of contraception’s less popular choices, with many people favouring the coil or the combined pill. You might’ve heard of it, but have you ever considered using it? Get the lowdown on all you need to know about the vaginal ring, which is a form of combined contraception.

What is a vaginal ring?

The vaginal ring is made of a type of soft plastic unable to dissolve in the body. Once placed inside the vagina, it releases a dose of oestrogen and progestogen into the bloodstream in order to prevent pregnancy, similar to the combined pill and contraceptive patch. Around 5cm in diameter, it kind of resembles a glowstick. Obviously, without the glow (although that would be strangely awesome).

At the Lowdown, we have come up with an easy guide about different contraceptives to help you to find the most effective option. If we look at 100 sexually active women using the ring for a year, with perfect use less than 1 will get pregnant but if we look at typical use 7 women will get pregnant during that year.

You can start using the vaginal ring at any time in your cycle. If you start within the first 5 days of your period starting, you will be protected from pregnancy straight away (if you have a short cycle then speak to your doctor or nurse). Any other time in your cycle and you’ll need to use condoms or other contraception for seven days. 

It can be left inside vagina for 21 days, after which you remove it and have a 7 day ring-free break, as you may do with the combined pill. It’s very common that during this break you may have a withdrawal bleed. Once your break is over, pop in a new ring for another 21 days. If you’re someone who forgets to take the pill often, then the ring could be a reliable option for you. We have also put together a handy guide about how to use combined contraception continuously and avoid having the 7 day break and associated bleeding.

What’s the difference between the NuvaRing and the SyreniRing?

The SyreniRing and NuvaRing are practically identical; they both contain the same types and amounts of oestrogen and progestogen. The key difference between these vaginal rings is that the SyreniRing has a shelf life of two years, and doesn’t need to be refrigerated, which means you can be prescribed up to a year’s supply at once. The NuvaRing however, must be refrigerated before being dispensed, and then used within 4 months. Store your Nuvaring at room temperature, in a safe place away from sunlight.

How does the vaginal ring work?

The vaginal ring works to prevent pregnancy in three ways:

  • Primarily, it changes your body’s hormonal balance to stop ovulation (meaning you don’t produce an egg).
  • It causes the mucus in the neck of the womb (cervix) to thicken and form a mucus plug. This makes it difficult for sperm to get through to the womb (uterus) to fertilise an egg that may have been released.
  • It also makes the lining of the womb thinner, which reduces the chances of a fertilised egg becoming attached to the womb.

Where can I get a vaginal ring?

Okay, so you’ve decided you want to try out the vaginal ring. It’s available at some GP practices, young peoples’ services, sexual health and contraception clinics. However it’s always best to check if this is something your local practice can offer ahead of making an appointment, and some clinics will only offer services up to a certain age.

At the appointment, your GP or healthcare professional will check your medical history, make sure you’re not pregnant and run blood pressure and weight checks to make sure you’re eligible for the vaginal ring.

If you already use the vaginal ring, you can also order the SyreniRing directly from The Lowdown.

Bear in mind that it may not be suitable for you if; you take medicines that could interact with the ring, have had a previous blood clot, high blood pressure, a high BMI, diabetes, or are over 35 and a smoker.

How to insert a vaginal ring

Now, you’ve picked up your first vaginal ring and I bet you’re thinking, “how on earth do I get it in?!” The placement of the vaginal ring is similar to fitting a tampon or menstrual cup. It can be a bit fiddly at first, but once it’s in it should stay in place. 

Here’s how to insert a vaginal ring:

  • First things first, wash your hands. Squeeze the ring between your thumb and gently insert it into your vagina. Push in until it feels comfortable and secure – similar to how a tampon feels – and should be far enough inside that you can’t feel it. According to the NHS, unlike the diaphragm or cap, the ring does not need to cover the entrance to the womb to work.

You can start using it at any time during your menstrual cycle providing you are not pregnant. If you fit it on the first 5 days of your cycle, you will be protected from pregnancy right away. If you fit it at any other time in your cycle then you will need to use condoms for seven days or avoid having penetrative sex. Them’s the rules.

How to remove a vaginal ring

To stop using your vaginal ring, simply remove it from your vagina. To remove it, place one finger into the vagina, hook the finger under the ring, and gently pull it out. Put it in the bag provided and throw it in the bin.

If the vaginal ring comes out and has been out for less than 48 hours, it can be washed in lukewarm water and reinserted with no additional contraception needed. See the NHS guide about what to do if it has been out for longer than 48 hours.

Pros and cons of the vaginal ring


  • The vaginal ring should not interrupt sex
  • It’s easy to insert and remove – once you get the hang of it
  • You don’t have to think about it everyday
  • It’s still effective if you are sick or have diarrhoea
  • It may help with PMS symptoms
  • Bleeds can become lighter, more regular and less painful
  • It can have additional health benefits which include reducing the risk of ovarian, endometrial and bowel cancers as with all combined contraceptives
  • It has no long-term effect on your fertility


  • It may accidentally fall out during sex or at other times of the month if not properly inserted

  • It may cause temporary side effects which can include increased vaginal discharge, headaches, nausea, breast tenderness and mood changes
  • Slight increased risk of developing blood clots in your veins and arteries
  • It does not protect you against STIs
  • You need to remember to change it every 21 days, and replace it after your break if you have one
  • Some medicines might make it less effective

Who should use the vaginal ring?

  • Those wanting contraception that doesn’t need to be remembered every day
  • If you want your bleeds to be regular, lighter and less painful

What does The Lowdown say?

While the vaginal ring is one of the less popular methods of contraception on The Lowdown, we still have a great range of reviews on the vaginal ring. You can also see separate reviews on Syreniring and Nuvaring. Here is what a few of our reviewers have to say:

“It’s a great contraception and it worked perfectly for the first two years, but I started having a lot of headaches and dark spots on my face after that.”

“Loss of sex drive was the only side effect I had. But, the NuvaRing affects me much less than any other birth control I have tried.”

“I absolutely loved the NuvaRing. As a college athlete, I had a busy schedule and my schedule varies a lot day-to-day, so being able to leave the ring in for three weeks at a time without worry was amazing. I didn’t experience any side effects beyond my normal period moodiness and cramps. I was able to leave the ring in during sex without too much interference and didn’t have any issues with discomfort. I developed a blood clot almost five years after being on the ring. It couldn’t be determined whether the clot was related to hormonal birth control or not…”

“Pros: lighter periods, really regular. Cons: Breast pain, I felt discomfort every time I groped my breasts.”

“This contraception is the best I have tried. I have been on the pill and patches before trying the ring and I would never go back now. For someone who is quite forgetful this is the best solution, it is as simple as putting in a non-applicator tampon, it stays there for three weeks – your partner will feel it during intercourse but I haven’t had any complaints!”

Overall, the contraceptive vaginal ring is super simple and easy to use. It’s great for busy lifestyles, but you need to make sure you’re comfortable and confident inserting it yourself.
