Worth a test...: Whenever you have changes in your usual menstrual cycle, especially if you are usually fairly regular in timing and quality/quantity of bleeding, it is a good idea to do a home pregnancy test to see if this is the cause. If the test is negative, then the list of other possible causes is long and probably warrants a visit to your doctor.
