Abstract
A pharmaceutical composition comprising an active contraceptive drug and one or more pharmaceutically-acceptable excipients.

The pharmaceutical composition is administered daily to a patient having a BMI of about 25 kg/m2 or more for at least a portion of a treatment cycle. The pharmaceutical composition does not cause a number of days of bleeding events in the patient exceeding an average of 15% per treatment cycle in consecutive treatment cycles of administration after an initial treatment cycle of administration.
