NuvaRing? is a comfortable, flexible ring about 2? in diameter. You insert it into your vagina once a month* ? the exact position isn?t important for it to work. Once inside, NuvaRing? releases a continuous low dose of hormones to prevent pregnancy.

NuvaRing? is as effective as the Pill when used as directed, but you don?t have to take it every day. You leave NuvaRing? in place for 3 weeks, then remove it for a 1-week ring-free period. You should get your period during this ?week off.? (Using NuvaRing? as prescribed, you will continue to be protected from pregnancy during the ring-free week.) Exactly 1 week after you take NuvaRing? out, you insert a new one.
