A period is generally considered late if it is more than 7 days past the expected start date based on your usual menstrual cycle. Menstrual cycles typically range from 24 to 38 days, and variations of a few days are common and usually not a cause for concern. If a period is late by about 6 weeks or more, it is usually considered a missed period. Variations can occur due to many reasons including stress, weight changes, exercise, hormonal birth control, or health conditions, and pregnancy is a common cause of a late period. For regular cycles, a delay beyond a week is usually considered late enough to consider testing for pregnancy or seeking medical advice if pregnancy is ruled out. Persistent or very irregular delays may warrant medical evaluation. In summary:
- Periods 1-6 days late: often not concerning.
- Periods 7 days or more late: considered late.
- Periods 6 weeks or more late: considered missed.
- Causes beyond pregnancy include stress, hormonal changes, and health conditions.
This timing and the interpretation also depend on individual cycle regularity and health context.
