Vaginal ring

The vaginal ring is a small, flexible plastic ring with hormones that you place in your vagina to prevent pregnancy.
You place the ring into the vagina, leave it in for 3 weeks, and remove it on week 4, while you get your period.
The vaginal ring is about 91% effective. This means that out of 100 couples using the ring to prevent pregnancy, about 9 of them will get pregnant over one year.¹

The vaginal ring contains the hormones estrogen and progestin to stop you from getting pregnant.
The ring releases these hormones into your body through the vagina.
The hormones in the ring work by:
- Stopping your ovaries from releasing eggs. When eggs aren’t released, you can’t get pregnant.
- Making the mucus in your cervix too thick for sperm to pass through. This prevents sperm from meeting an egg.

To insert a ring, squeeze the sides of the ring together with your fingers. Gently push it into your vagina. There’s no perfect way to insert it. As long as you can’t feel it while you’re walking around, you’ve inserted it correctly.
Leave the ring in your vagina for 3 weeks. You can have sex with the ring in.
At week 4, remove the ring by hooking your finger under the ring and gently pulling it out of your vagina. Throw it away.
- Most vaginal ring brands (such as NuvaRing) work for one month and should then be thrown away.
- Annovera is a different vaginal ring that you can reuse for up to 12 months
After removing the ring, you should get your period within a few days. At the end of week 4, insert a ring to start the cycle over. Place the new ring after 7 days even if your period isn’t over.
Make sure you fill your prescription for the ring on time so you can remove and insert the ring at the right times for your cycle.
If the ring slips out, rinse it off and put it back into your vagina. If the ring is out for more than 3 hours before you put it back in, use condoms for the next 7 days.

The vaginal ring is about 91% effective in preventing pregnancy.
You can leave the ring in during sex. Your partner usually won’t be able to feel the ring during sex.
You may have lighter, more regular, or less painful periods.
The ring helps prevent or lessen acne, body hair, premenstrual syndrome (PMS), anemia, and ovarian cysts.
It’s temporary. You can stop using it whenever you want to try getting pregnant.
The hormones in the ring help decrease your risk of endometrial (uterine) and ovarian cancers.

The vaginal ring doesn’t protect against sexually transmitted infections (STIs/STDs), including HIV. Even if you use the ring, you should use a condom every time you have sex to reduce your chances of getting or spreading STIs.
It may cause an increase in vaginal discharge.

About 5 out of 100 users may notice mild side effects like headache, nausea, mood changes, or breast tenderness.

If you don’t use the ring correctly, you could get pregnant.
Blood clots in the veins and arteries are a serious, but uncommon, side effect of using the vaginal ring. Blood clots, such as deep vein thrombosis and pulmonary embolus, can be serious. This risk is similar with most birth control pills.
If you have uncontrolled high blood pressure, you shouldn't use the vaginal ring. It can increase your risk of stroke.
Smoking and using the vaginal ring can increase your risks for blood clots in your veins and arteries, high blood pressure, and stroke.

If you have medical conditions, talk with your health care provider to see if the vaginal ring is a good option.
