How can doctors test to see if your missed periods were from stress or nothing more serious?

Missed periods: There are any number of reasons for missed periods including pregnancy, malnutrition, extreme exercising, polycystic ovaries and certain medications including some birthcontrol pills. Your physician would need to review your history to determine which tests would be most appropriate. These can include urine pregnancy tests, hormone levels, pelvic examination, ultrasound or even a ct scan.
