A period is generally considered late if it is 5 or more days past the expected start date based on your usual cycle length. Typical menstrual cycles range from 21 to 35 days, with some variation being normal. If you usually have a regular cycle and your period does not start within about a week of when expected, it is considered late and may warrant attention or a pregnancy test if sexually active. Factors like stress, lifestyle changes, hormonal imbalances, and health conditions can cause delays. If your period is significantly late (e.g., more than a week or eight days) and you are sexually active, it is advisable to take a pregnancy test and consult a healthcare provider if uncertain or if the cycle irregularity persists.
