Treatment Cycles
UPA only: During the first treatment month, 1 dose of the study medication ulipristal acetate (UPA) will be given when the follicle is a certain size (approximately cycle day 10). Following this, there will be daily study visits for 7 days unless evidence of ovulation occurs earlier. Cycle 1: Ulipristal Acetate UPA+COC: During the second treatment month, 1 dose of the study medication ulipristal acetate (UPA) will be given when the follicle is a certain size (approximately cycle day 10) and then 2 days later start birth control pills. Following this, there will be daily study visits for 7 days unless evidence of ovulation occurs earlier. Cycle 3: Ulipristal Acetate and Levonorgestrel (LNG)/Ethinyl estradiol birth control pill
