To insert:

Just squeeze NuvaRing® between your thumb and index finger and gently insert it into your vagina. NuvaRing® will conform to fit your body. If you feel NuvaRing®, simply slide the contraceptive ring farther into your vagina. The exact position is not important for NuvaRing® to work and the muscles of your vagina should keep NuvaRing® in place. Put NuvaRing® where it is comfortable for you. To remove:

You can remove NuvaRing® by hooking the index finger under the forward rim or by holding the rim between the index and middle finger and pulling it out.
