Gynecology >> Vaginal Contraception (NuvaRing)


NuvaRing is an easy-to-use birth control option that, when used as directed, is just as effective as the Pill. But with NuvaRing, you don’t have to take it every day in order to get a full month of pregnancy protection. In a given 1-month period, NuvaRing must be inserted into your vagina, removed after 3 weeks, and a new ring must be inserted no more than 7 days later.

That’s because NuvaRing is a different form of birth control. It’s a flexible ring about 2” in diameter that you insert vaginally once a month. Once inside, NuvaRing releases a continuous low dose of hormones to prevent pregnancy.

NuvaRing contains 2 types of hormones: estrogen and progestin, which work together to prevent your ovaries from producing mature eggs. These are the same hormones found in the Pill, and they work the same way in your body even though they are administered differently with NuvaRing.

With NuvaRing, hormone release is activated once the ring comes into contact with your vagina. The hormones are then absorbed and distributed into your bloodstream.

When used as directed, NuvaRing works as well as the Pill—it is 99% effective in preventing pregnancy.

NuvaRing® Works With Your Cycle

Over the course of 3 weeks, NuvaRing releases a continuous low dose of estrogen and progestin. Higher estrogen and progestin levels signal your brain not to release the hormones that cause egg maturation. Without an egg ready to be released into the fallopian tube, ovulation cannot occur.

A few days after you remove NuvaRing, the lining of the uterus begins to shed and you get your period.

Your new cycle begins again on the 29th day, which is the first day you insert your new ring after being ring-free for a week. It is important that you insert your new ring on the same day of the week each month.

If you are already using NuvaRing, you can help you keep track of your schedule by downloading this simple tool.
