AB Uterine  bleeding  may  occur  in  the  absence  of  current  or  recent  pregnancy,  during  pregnancy,  or  in  the  postpartum  period.1  Abnormal  uterine  bleeding  (AUB)  is  a  term  that  defines  menstrual  bleeding  that  occurs  on  an  abnormal  schedule,  for  an  abnormal  duration  of  time,  or  with  an  abnormal  quantity  of  blood  loss.2-6  The  term  dysfunctional  uterine  bleeding  is  no  longer  used.7,8  Dysfunctional  uterine  bleeding  is  a  general  term  that  was  used  to  describe  irregular  bleeding  in  the  nonpregnant  patient.  AUB  can  manifest  as  heavy  menstrual  bleeding  (HMB).  HMB  is  cyclical  or  ovulatory  bleeding  and  was  previously  termed  menorrhagia.  Intermenstrual  bleeding  (IMB)  refers  to  bleeding  that  occurs  between  menses.  This  was  previously  termed  metrorrhagia.  IMB  often  has  a  cervical  etiology.  Approximately  3%  of  women  have  physiologic  IMB  associated  with  ovulation.9  Approximately  66%  of  women  who  have  had  one  or  more  cesarean  births  have  a  defect  in  the  uterus.  This  is  reported  as  regular  postmenstrual  spotting.10  Irregular  AUB  is  caused  by  ovulatory  dysfunction  (AUB-O)  and  is  often  reported  as  no  cycle  for  2  to  3  months.  When  cycles  occur,  they  are  often  heavy.
