Brief Summary: This is an open-label prospective, multicenter, randomized trial to compare continuation rates into the fourth cycle of women using either the NuvaRing or OrthoEvra. Five hundred women will be recruited at 9 centers nationwide to be randomly assigned to use either the NuvaRing or OrthoEvra for four months.
