Etonogestrel and Ethinyl Estradiol Nuvaring is a monthly vaginal ring containing progestin and estrogen, two hormones that prevent pregnancy. The ring is left in for three weeks, removed and then replaced a week later. Read more about birth control.
Start Consultation*Prescription treatment requires a virtual medical consultation with a medical provider to determine if a prescription is appropriate.
After starting the ring, you may have
  • Irritation inside your vagina or on your cervix
  • Ring slippage causing discomfort
  • Headaches
  • Nausea
  • Sore breasts
  • Changes in your periods (early, late, or stopping altogether while on the pill)
  • Spotting (bleeding between periods or brown discharge)
  • Weight gain
  • Abdominal pain
  • Mood changes, including a change in sex drive
  • Skin changes like acne

The good news is that these side effects usually go away in 2-3 months. So, if you just started the ring and you have side effects that bother you, try to stick it out and give your body a chance to adjust to the hormones.

If you have any questions about your birth control pills, request a medical provider callback from your patient dashboard.

How the ring works: 
  • Once you place the ring in your vagina, it releases a continuous low dose of hormones that helps prevent pregnancy.
  • The vaginal ring prevents pregnancy 96%-99% of the time when you use it correctly.
  • The ring is used in a 4-week cycle. Keep the ring in your vagina for 3 weeks (21 days) and then remove it for a 1-week (7-day) break.
  • Regularly check that the ring is still in your vagina (for example, before and after sex) to ensure you do not get pregnant.
  • Because the ring is releasing hormones, it does not have to be in a specific position to work. 
  • Most people don’t feel the ring when it is in place.
How to use the ring: 
  • The ring should be inserted and removed on the same day of the week and at the same time. (For example, if you insert your ring on a Monday at 8:00 AM, you should remove it on the Monday 3 weeks later at 8:00 AM.) Typically you’ll get your period during the 1-week break that you remove your ring.
  • Insert a new NuvaRing after the 1-week break. The new ring should be inserted on the same day of the week and at the same time that you inserted it the last month, even if your period has not stopped.
How to insert the ring: 
  • Wash and dry your hands.
  • Hold the ring between your thumb and index finger and press the sides of the ring together.
  • Insert the folded ring into your vagina and gently push it further up into your vagina using your index finger.
  • When you insert the ring it may be in different positions in your vagina, but it doesn’t have to be in an exact position for it to work.
  • If the ring feels uncomfortable, you may not have pushed it far enough into your vagina. Use your finger to gently push the ring as far as you can. Rest assured that once inserted into the vagina, there is no danger of the ring being pushed too far or getting lost.
How to remove the ring: 
  • Wash and dry your hands.
  • Make sure to remove the ring 3 weeks after insertion on the same day of the week and at the same time of day that it was inserted.
  • Put your index finger into your vagina and hook it through the the ring. Gently pull downward and forward to remove the the ring and pull it out.
  • Throw the ring away (do not flush it in the toilet)
  • Insert a new ring 1 week (7 days) after, on the same day of the week and at the same time that the previous ring was removed, even if your period has not stopped.

You can also use a condom every time you have penis-in-vagina sex. That way you’ll be protected from STDs too.
