The pill can also be used to control [[dysfunctional bleeding]] or symptoms of [[polycystic ovary syndrome]]. They consist of a pill that women take daily and that contains doses of synthetic hormones (always a [[progestin]] and most often also an [[estrogen]]). In some types of pill the doses of hormones are adjusted to be in synchrony with the [[menstrual cycle]] (two- or three-phase pills), while others keep a constant level of the hormones.
