My Period

Menstruation & Your Cycle

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 57 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 2135 days.


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

To Irealywantmyperiod! Every girl is different and so are periods when they start. Usually for the first two years your periods will be irregular. That means they could start and come at any given time. "Always expect the unexpected" was what my Mom told me. For example, you might get it three months in a row then skip three months in a row. Maybe get it every other month. Check yourself each time you use the restroom. Start wearing pantiliners (if you haven't already). They will protect your clothes and keep you feeling fresh. Start carrying supplies with you: pads, tampons (when you are ready to use them), wipes, Advil, Aleve, Midol, etc. (for cramps), change of panties, quarters for the machines, etc. Try to use the handicap stall, if available. That stall usually gives you more to change your supplies and your clothes, if the need arises. If you have any questions, just ask.
