Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Continued withdrawal bleeding was defined as any withdrawal bleeding that continued into the "expected non-bleeding period" of the next cycle. Expected non-bleeding period: NOMAC-E2: 21-day period starting on Day 4 of the cycle; LNG-EE: 21-day period starting on Day 1 of the cycle.
