Do not use NuvaRing
The NuvaRing should not be used by pregnant women or by women who have recently given birth (within 4 weeks).
Some conditions may make the NuvaRing dangerous for you to use.

Other factors that make it dangerous to use the NuvaRing include certain hepatitis C medication, if you are about to have major surgery, or if you smoke and are over the age of 35. If these apply to you; find an alternative contraceptive.
