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.
Irregular periods: what does irregular mean? The average length of a Menstrual Cycle is around 28 days, and menstrual bleeding usually lasts between 2- 7 days. If your period varies from the average length and flow, your period may be irregular. Donât worry, irregular periods are common and a missed period does not always mean something serious.
