Sometimes women have menstrual cycles that are not normal. These abnormalities range from no period at all (amenorrhea), frequent bleeding (metrorrhagia), to very heavy long periods menorrhagia. Your provider can evaluate and treat these disorders using medicines or surgery, whichever is the most appropriate for your individual situation. Sometimes a sonogram will be performed. Sometimes a biopsy is recommended. In preparation for your visit it is useful to keep a menstrual diary. This can be done on a small calendar which can be carried in your purse or pocket or kept by your sink or nightstand.
