How is abnormal menstruation (periods) diagnosed?
If any aspect of your menstrual cycle has changed, you should keep an accurate record of when your period begins and ends, including the amount of flow and whether you pass large blood clots. Keep track of any other symptoms, such as bleeding between periods and menstrual cramps or pain.
Your doctor will ask you about your menstrual cycle and medical history. He or she will perform a physical examination, including a pelvic exam and sometimes a Pap test. The doctor might also order certain tests, including the following:
- Blood tests to rule out anemia or other medical disorders
- Vaginal cultures, to look for infections
- A pelvic ultrasound exam to check for uterine fibroids, polyps or an ovarian cyst
- An endometrial biopsy, in which a sample of tissue is removed from the lining of the uterus, to diagnose endometriosis, hormonal imbalance, or cancerous cells. Endometriosis or other conditions may also be diagnosed using a procedure called a laparoscopy, in which the doctor makes a tiny incision in the abdomen and then inserts a thin tube with a light attached to view the uterus and ovaries
