The vaginal ring is a prescription method of birth control. It’s also known by its brand name, NuvaRing. The vaginal ring is a small, flexible, plastic ring that you insert into your vagina to prevent pregnancy. It’s about two inches around.
The vaginal ring prevents pregnancy by continuously releasing synthetic estrogen and progestin. These hormones are absorbed into your bloodstream. They prevent your ovaries from releasing eggs to be fertilized. The hormones also thicken your cervical mucus, which helps prevent sperm from reaching the egg.
The ring is very simple to use. To insert and remove the ring:
You should get your period during the week that you are not using the ring. One week after removing it, insert a new ring. You should insert the new ring even if you are still menstruating.
It is important that you remove or insert the ring on the same day of the week. For example, if you insert a ring on Monday, you should remove it on a Monday three weeks later. Then, you should insert your next ring on the following Monday.
If the ring falls out, rinse it off and put it back in. If the ring is out of your vagina for longer than three hours, use backup contraception. The ring may fall out when you:
If you use it properly, the vaginal ring can be very effective. It is one of the more effective methods of contraception. According to the Centers for Disease Control and Prevention, typically only 9 percent of women who use the ring will get pregnant.

Talk to your doctor about your specific risk factors. Some women in high-risk categories, including women who smoke and are older than 25 years, shouldn’t use estrogen-containing contraceptives.
The vaginal ring is a birth control option that many women find easy and convenient. When deciding on a birth control method that’s right for you, think about all of your options. If you think the vaginal ring is a good choice, talk to your doctor.
