Heavy menstrual bleeding (HMB), previously known as menorrhagia or hematomunia, is a menstrual period with excessively heavy flow. It is a type of abnormal uterine bleeding (AUB). [ 1 ] [ 2 ]
The initial workup includes exclusion of pregnancy and cancer, by performing a pregnancy test, a pelvic exam and a gynecologic ultrasound. Further workup depends on outcomes of the preceding tests and may include hydrosonography, hysteroscopy, endometrial biopsy, and magnetic resonance imaging. [2]
Intermenstrual bleeding (IMB), or metrorrhagia, is vaginal bleeding at irregular intervals between expected menstrual periods. [1] It may be associated with bleeding with sexual intercourse . [ 2 ] The term metrorrhagia, in which metro means measure and -rrhagia means abnormal flow, [ 3 ] is no longer recommended.
Dysmenorrhea, also known as period pain, painful periods or menstrual cramps, is pain during menstruation. [4] [5] [2] Its usual onset occurs around the time that menstruation begins.

Normal menstruation is not considered a gynecologic hemorrhage, as it is not excessive. Hemorrhage associated with a pregnant state or during delivery is an obstetrical hemorrhage.
It can be distinguished from metrorrhagia by its regularity. [3] Polymenorrhea can be contrasted with oligomenorrhea, in which menstrual cycles are greater than 35 or 37 days in length. [3] [12] The condition can also be distinguished from polymenorrhagia, which is a combination of polymenorrhea and menorrhagia (heavy menstrual bleeding). [1]
