Take pregnancy test: Many things, including stress, can cause a late or missed period. However, the most common cause is still pregnancy, so definitely take a test to make sure you're not pregnant. If the test is negative, keep a calendar of your cycle for the next few months so that if your period continues to be irregular you can discuss with your doctor.
