When counseling a woman about the norelgestromin/ethinyl estradiol patch (Ortho Evra®), you advise that:

a) "Building up" of menstrual flow can occur with long-term use.
b) Abdominal pain can occur more frequently when compared to oral contraceptives.
c) Breast discomfort can occur more frequently when compared to oral contraceptives.
d) Fertility is often delayed for a number of months after discontinuation.
