Or some women just double-ovulate, or triple-ovulate, and never catch on because they've never charted their cycles. Pills are designed to catch that first ovulation but not the second or third. Not entirely sure about how the IUD interacts with the system, but I am aware of a couple of women who are multiple-ovulators who have conceived while an IUD was properly installed.

Sorry about the threadjack.
