How long can stress delay my period?

Indefinitely: Stress can dysregulate your menstrual cycle -- making periods come sooner or much later than expected. Periods may even be absent. If it's possible you could be pregnant though, it's best to check a home pregnancy test. That is the most common cause of delayed menses in a woman with regular periods.

CONSIDER: At 49 it's time to consider menopause, irregular periods etc. If there's a great deal of stress you want to lower the stress. If you can't do it on your own get a therapist to help. The stress may be more of a problem than the period.
