Treatment: Drugs - VOX
Treatment: Drugs - Norgestimate/ethinyl estradiol

Experimental: SOF/VEL/VOX + VOX - Part A: Participants without a documented history of taking norgestimate/ethinyl estradiol for at least one menstrual cycle will receive norgestimate/ethinyl estradiol. Participants with a documented history of taking norgestimate/ethinyl estradiol may enroll directly into Part B of the study.

Treatment: Drugs: VOX
100 mg tablet administered orally once daily

Treatment: Drugs: Norgestimate/ethinyl estradiol
Norgestimate 0.180 mg/0.215 mg/0.25 mg/ethinyl estradiol 0.025 mg tablet administered orally once daily according to the package insert
