This page is for the generalized approach to undifferentiated vaginal bleeding in<unk>  women
Normal menstruation:
28 +/- 7 day cycles
3-7 days of bleeding
Usual amount bleeding per period 10-35 cc
Each normal sized tampon or pad holds 5 cc when soaked through
Bleeding from the uterine corpus that is irregular in volume, frequency or duration, in absence of pregnancy, is abnormal
Vaginal bleeding before the age of menarche may be the result of infection, trauma (ex. sexual assault, foreign body) or a structural lesion
28 +/- 7 day cycles
3-7 days of bleeding
Usual amount bleeding per period 10-35 cc
Each normal sized tampon or pad holds 5 cc when soaked through
Menorrhagia: >7 day (prolonged) or >80 mL/day (excessive) uterine bleeding at regular intervals
Metrorrhagia: irregular vaginal bleeding outside the normal cycle
Menometrorrhagia: excessive irregular vaginal bleeding
Intermenstrual bleeding: variable amounts between regular menstrual periods
Midcycle spotting: spotting just before ovulation (due to decline in estrogen)
Polymenorrhea: frequent and light bleeding
Postcoital bleeding: vaginal bleeding after intercourse, suggesting cervical pathology
