How Long Should a Period Last?

Is this normal? Figure out what is normal for you

When you first start menstruating, the length of your period won't be regular—it could last one day or ten days. The average length of a period is 5–7 days.

When you first start to menstruate, the cycle could be very irregular; starting, stopping, and starting again. For example, you could have one period and then wait as long as six months for the next one! This isn't unusual. Until your body adjusts to your cycle, your period may be unpredictable. But after that, your menstrual cycle should be fairly regular during most of your menstruating years. If your period continues to be very irregular, you should see your doctor. The length of time between periods can be anywhere from 21–35 days.

Use the period predictor to learn more about your individual cycle:

What date did your last period start?

How long is your menstrual cycle*?

What is a cycle? A cycle is the number of days between the first day of your last period and the first day of your next period.

How long do your periods last?

Remember that if you just started getting your period, your cycle can be a bit irregular. So don’t worry if your periods don’t follow the period prediction exactly-the Period Predictor is intended as a guide only.

@Dancegirl13! I suggest to eat heathlier. You can still have junkie food, but not as much. Also, has anything else been happening? Sometimes, you might not realize it, but other, random, things can happen that might affect the flow of your period. Hope this helps!
