Hi, the normal menstrual cycle lasts between 21 and 35 days. 28 is just the average.
How many days does your cycle usually last? If you are irregular occasionally, you shouldn't worry about it too much, as stress or a temporary hormonal imbalance can cause this. But if you are constantly irregular you should go see your doctor.
