How Many Days Should a Period Last?

Just as no two women are exactly the same, no two menstrual cycles are the same. But there are some guidelines when it comes to the length of your periods and other factors, like flow and frequency.

How long should my period last? 

Before considering whether your period is too long or too short, you need to understand how doctors think about normal periods. What’s normal for one woman might be unusual for another, making it more difficult to know when something’s wrong.

On average, we consider normal menstrual cycles to last 21-35 days, and normal periods to last as few as three days or as long as seven days. With such a wide range of what’s considered normal, we also take into account what has been normal for you historically.

While very short periods, those lasting a day or two, may sound like a dream to some women, they could be the sign of an underlying health condition, especially if your cycle suddenly becomes shorter.

As with long periods, there are many possible causes of very short periods. Some reasons women experience very short periods include:

While one short period probably isn’t cause for concern, contact Dr. Morales if your period becomes short after being regular or if you experience other symptoms with a short period, like heavy bleeding or skipping several periods.
