(Newser) – Women with irregular periods usually blame stress or other lifestyle factors, and often use hormonal birth control to make their cycle regular.

After starting on the Pill, a woman may think, "'Oh, it looks like things are fine now, because my periods are coming,'" said a POI researcher.
