Question

Quizplus · Accepted Answer

The most common reason for failure of the contraceptive pill is when the woman forgets to take the pill for a day or two or so. It is important to take the pill every day at the same time for maximum effectiveness. Other factors such as switching brands or the pill not containing enough estrogen can also contribute to failure but are less common than missed doses. Sexual partner fertility also does not affect the effectiveness of the pill.
