Exclusion Criteria:

• Participant has a history of discontinued use of oral contraceptives (OC) for medical reasons

• Participant has any medical reason that would contraindicate the administration of OC (per label)

• Participant has used any of the following within the specified time period prior to first dose of study medication:

1. Oral contraceptive or oral hormone replacement therapy within prior 30 days

2. Implanted hormonal contraceptives within prior 6 months

3. Injectable contraceptives within prior 12 months

4. Topical controlled-delivery contraceptives within prior 3 months

5. Hormone-releasing intrauterine devices ('coils') within prior 3 months

• Participant has other relevant gynecological disorders (such as premature ovarian failure or endometriosis)

• Participant has any clinically relevant electrocardiogram (ECG) finding at the Screening Visit or at Baseline (Day -1) that, in the opinion of the Investigator, increases the risks associated with participating in the study. In addition, any study participant with any of the following findings will be excluded:

1. QT interval corrected for heart rate using Bazett's formula (QTcB) or Fridericia's formula (QTcF) >450 ms in 2 of 3 ECG recordings;

2. other conduction abnormalities (defined as PR interval =220 ms);

3. irregular rhythms other than sinus arrhythmia or occasional, rare supraventricular or rare ventricular ectopic beats. In case of an out-of-range result, 1 repeat will be allowed. If the result is out-of-range again, the study participant cannot be included

Secondary	Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) in Part 1	An adverse event (AE) was any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. TEAEs were defined as AEs with a start date/time on or after the first dose of study medication (OC or PSL) or any unresolved event already present before administration of study medication that worsened in intensity following exposure to the treatment.

From Baseline up to Safety Follow-Up during Treatment Sequences A and B (up to Day 46)
Secondary	Percentage of Participants With TEAEs in Part 2	An AE was any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment.
