when is a period considered late
Because there is variability for cycles, if you have a period that falls outside of the 35 day mark, donât automatically assume the worse. Menstrual cycles can vary each month â a day or two late here, or a few days early there â for a number of reasons. As long as you have a period every month, you are probably fine. However, you will probably want to make an appointment with a gynecologist to get checked out if your cycle is over 40 days.
