What should I do if I forget to put in a new NuvaRing?
After 3 weeks of use, NuvaRing should be removed for a 1-week break and then a new one should be inserted no more than 7 days later. If the ring-free interval has been extended beyond 1 week, the possibility of pregnancy should be considered, and you must use an additional method of birth control (such as condoms or spermicide) until you have used NuvaRing continuously for 7 days. If you know or suspect you are pregnant, do not use NuvaRing. See your doctor as soon as possible.
