Reporting Groups
  Description
All Participants All participants were given a low dose oral contraceptive (Aviane) cyclically for 2 months
Study Arm #1 (Aviane and Aviane) A very-low dose oral contraceptive given cyclically (21 days of active pills/cycle with a 7 day hormonal-free interval) for 2 cycles (56 days). A very-low dose oral contraceptive given continuously for 56 days (20mcg EE component, 28 days of active pills/cycle with no hormone free interval)
Study Arm #2 (Aviane and Portia) A very-low dose oral contraceptive given cyclically (21 days of active pills/cycle with a 7 day hormonal-free interval) for 2 cycles (56 days). A low dose oral contraceptive given cyclically (30mcg EE component, 21 days of active pills/cycle with a 7 day hormonal-free interval) for two cycles
