The doctor will ask about your symptoms and health history. You will also be asked about your periods. A physical exam will be done. A pelvic exam may also be done.

Heavy Bleeding (Menorrhagia)


These tests may be done to look for a cause of heavy bleeding:

  • Blood tests—to measure hormones and check for bleeding disorders
  • Ultrasound—to view pelvic organs
  • Hysteroscopy—A tube is passed to the uterus through the vagina to view the uterus
  • Endometrial biopsy—tissue is scraped from the uterus and looked at using a microscope

Lack of Periods (Amenorrhea)

Blood Tests

A blood test will be done to find out whether the woman is pregnant. The test can also look for:

  • Too much or too little thyroid hormone
  • Too much prolactin in the blood
  • Too much or too little luteinizing hormone
  • Too much or too little follicle stimulating hormone

Genetic tests may also be done to find the cause.


An MRI scan may be done to check for pituitary tumor.
