Hypomenorrhea or hypomenorrhoea, also known as short or scanty periods, is extremely light menstrual blood flow. It is the opposite of hypermenorrhea which is more properly called menorrhagia.
For the purposes of clarity we will use the lower case pms for pre-menstrual syndrome and the upper case PMS for post menstrual syndrome. The definition of Post Menstrual Syndrome is the presence of one or more hormone induced irregularities in the two weeks after a woman finishes her period. This is often call Post Menstrual Dysphoric Disorder.
