OC containing levonorgestrel and ethinyl estradiol + GSK126574EXPERIMENTALEligible subjects will enter a run-in-period of 21 days (may extend to 49 days) to stabilize on OC containing levonorgestrel and ethinyl estradiol in order to synchronize the menstrual cycles of multiple subjects. Subjects completing run-in-period will enter Treatment period 1 and will be dosed OC once daily on Days 1 to 10. At day 11 subjects will enter Treatment period 2 and will be dosed with OC containing levonorgestrel and ethinyl estradiol + 744 once daily on Day 12 to 19. Subjects completing Treatment period 2 will have 7 OC free days (Day 22 to 28) during which withdrawal menses should occur. Subjects will then be followed up for 7 to 14 days (Day 28 to 35/49).
