Footnotes
Percentages are based on women who used oral contraceptive pills in the past 4 weeks and had sexual intercourse in the past 12 months, who were asked the question “Still thinking about the past 4 weeks, how many pills that you were supposed to take did you miss? Would you say you never missed a pill, missed only one pill, or missed two or more pills?”
Estimates are based on interviews of the U.S. household population aged 15–44 years.
