Tips
Instead of tapping the pencil icon, tap and hold your finger on a date on the calendar to add or
edit a period.
Log your period consistently for more personalized predictions.
Why can’t I log or edit a period or female health details in the Fitbit app?
If a period doesn’t meet the following requirements, you may receive an error and be unable to log the
period:
You can only add or edit current or past periods and details.
A period must be at least 1 day.
You can log a period of up to 60 days (on Windows 10 devices, the maximum is 10 days). If your
period is longer, consider logging flow intensity details.
A cycle must be at least 11 days, and there must be a gap of at least 1 day between logged
periods. If you experience a gap in bleeding during your period, it’s still 1 period.
Note that If you attempt to log a period in the future or a period with less than a one-day gap between
periods, the pencil icon is unavailable. If you don’t see the pencil icon, make sure the period you’re
attempting to log or edit meets all of the requirements.
Why do I see a period I already deleted in the Fitbit app?
If you delete a confirmed period and you have predictions turned on, you’ll still see the predicted period
for that cycle. For more information about the icons and colors on your female health tracking calendar,
see How do I read the female health tracking calendar in the Fitbit app?
To turn off predicted periods, see How do I edit my female health settings?
How can I see trends in my Fitbit period data?
View your cycle trends to see your average period and cycle lengths, average estimated
ovulation day, and graphs of your past cycles and details. Note that you won’t see your average
estimated ovulation day if you turned off fertile window predictions. You must log at least 2
periods to see trends.
To see your female health trends:

indicates the intensity of your flow.
3. For information about a certain day of your cycle:
a. Tap and hold on the calendar that shows your cycle until a vertical line appears.
b. Drag your finger left or right to choose a day. The number in the top circle is the

Can I edit my average cycle or period length?
You can edit the average cycle length and period length you provided during setup; however,
these settings only affect your initial predictions.
Keep the following in mind:
Change your average period length to adjust the length of your initial period predictions. For
example, if you change your average period length from 5 days to 8 days, your predictions
adjust to reflect this change.
Edit your average cycle length to adjust the length of your entire cycle. If fertility predictions are
on, the predictions for your fertile window and ovulation day adjust based on the length of your
cycle. For more information, see our blog post Ovulation, Fertility, and Pregnancy: What It Really
Takes To Make a Baby.
To change your setup values for average cycle or period length:
1. Tap the Today tab , then tap the female health tile.

For some women, the estimated fertile window and period occur on the same day. You’ll see
purple shading on the calendar where the 2 windows overlap. Refer to the calendar icon for
details.
For more information, see our blog posts 4 All-Too-Common Period Myths—Debunked and
Ovulation, Fertility, and Pregnancy: What It Really Takes To Make a Baby.
How do I log bleeding between my periods?
If you experience bleeding before your period, sometimes known as breakthrough bleeding or
spotting, you can track it by logging flow intensity details. For more information, see How do I
log or delete female health details?
Do I see a period on the Fitbit female health calendar if I log flow
details?
Logging flow intensity details doesn’t add a period to your calendar. To add a period, see How
do I add, edit, or delete a period in the Fitbit app?
How do I confirm my period if it arrives early?
If your period arrives early, add it as a new period. Your future predictions automatically adjust.
For more information, see How do I add, edit, or delete a period in the Fitbit app?
How can I see my period information on my Fitbit device?
Swipe up from the clock face and scroll until you see your female health information.

How do I factory reset my Charge or Charge HR?
To restart or reboot your tracker by turning it off and on without deleting any data, follow the
instructions in How do I restart my Fitbit device? Restarting is an effective troubleshoot for
many scenarios.
The steps below provide a more complicated troubleshoot known as a "factory reset." Only
follow these steps if a Fitbit Customer Support agent asks you to do so or you're following the
firmware update troubleshooting steps for a Charge HR. You might be asked to do a factory reset
if:
You have a Fitbit Charge HR and you've tried all the steps in Why can't I update my Fitbit device?
Your Windows 10 device and the Fitbit app for Windows 10 can't detect your Charge or Charge
HR with Bluetooth.
You're using an Android phone and having difficulty with notifications or syncing.
You're using the Fitbit app for Android on a device running an older operating system (4.3 or
earlier) and the tracker was previously bonded to another mobile device.
A factory reset deletes any stored data, which includes all data that hasn't synced to your Fitbit account
and your alarms, goals, and notifications. After a factory reset you must set up your tracker again.
To factory reset your tracker:
1. Attach the charging cable to your tracker and plug the other end into a USB port.
2. Press and hold the button for approximately two seconds and without letting go of the button:
1. Remove the charging cable from your tracker.
2. Wait about seven to nine more seconds after removing the charging cable.
3. Let go of the button and hold it down again.

4. After "ALT" and a white screen flash, let go of the button and hold it down again.
5. After you feel a vibration, let go of the button and hold it down again.
6. After you see "ERROR," let go of the button and hold it down again.
7. After you see "ERASE," let go of the button. The tracker will turn off.
8. To turn your tracker back on, press the button or attach the charging cable (make sure to plug in
the other end of the cable). If the time on your tracker reads 0:00, the reset was successful.

What is Charge 2 made of?
The wristband that comes with Charge 2 is made of a flexible, durable elastomer material similar to that
used in many sports watches. It does not contain latex. Accessory wristbands are available in genuine
leather.
The buckle and frame on Charge 2 are made of surgical-grade stainless steel. While all stainless steel
contains traces of nickel and can cause an allergic reaction in someone with nickel sensitivity, the
amount of nickel in all Fitbit products meets the European Union's stringent Nickel Directive.
For our leather wristbands we selected tanneries that provide leathers widely used across the fashion
accessories industry. Following a careful selection process, the leather is colored and treated to achieve
a soft natural grain. The leather bands are crafted to maintain the natural look and feel of leather and
hand sorted to achieve consistency in texture. You can expect the bands to become more flexible over
time as they form to your wrist. Note that leather bands are not recommended for high-intensity
exercise. For information on caring for your leather band, see our Wear and Care page.\
