There Is A Wide Range Of Normal. Normal menstruation can last from one to eight days. For most women with regular menstrual cycles, their period will last on average three to five days. But that doesn't mean that anything is wrong if your period is a few days longer or shorter. Your period is unique to you and how much you bleed and for how many days you bleed will not be the same as anyone else.
When discussing irregular periods, it is helpful to first understand what a normal period is. While every woman is different, normal periods are typically described as occurring every 28 - 31 days, with bleeding lasting approximately five days. The average amount of blood loss during a normal period is two to eight tablespoons. While this is a general definition of normal periods, some women may experience menstruation differently. Thus, irregular periods might be characterized by other symptoms. What is irregular for one woman may be normal for another.
