Menstrual cycle disorders are common in women of reproductive age and can manifest as absent menses or menses occurring outside the normal frequency. Oligomenorrhoea is defined as infrequent periods occurring more than 35 days apart or fewer than eight periods a year. Amenorrhoea is defined as absence or abnormal cessation of menses for at least six months and can be primary or secondary. Primary amenorrhoea is absence of any menses by 15 years of age. Secondary amenorrhoea is absence of menses for more than six months in a previously menstruating woman.
