For more information about menstrual health details, see our blog post Everything You Need to Know About PMS And How to Cope.
To log positive or negative ovulation predictor kit (OPK) test results in the menstrual health tracking feature in the Fitbit app, see How do I log or delete menstrual health details? You can log OPK test results in the Fitbit app for iPhone, iPad, and Android phones.
Note: if your OPK provides high or peak fertility results instead of positive or negative results, log a positive OPK test result when you get a peak fertility reading.
How does logging a positive or negative test result affect my predicted period and fertile window?
When you log a positive OPK test result, your fertile window and next predicted period adjust based on your new ovulation day, which is the day after you log the positive test result.
Your future cycle predictions adjust based on the positive OPK test results you log, but past cycles don't change. If you delete a positive OPK test result in the current cycle, your predicted period and estimated fertile window predictions adjust.
If you log a negative OPK test result, your predicted period and estimated fertile window in the Fitbit app remain the same.
Why don't I see an estimated fertile window after logging a positive OPK test result?
In order to see your estimated fertile window in the Fitbit app after logging a positive OPK test result, note the following:
- If you log more than 2 positive OPK test results in a cycle, the Fitbit app can’t provide an estimated fertile window. Note that if you log 2 positive OPK test results in a cycle, you must log them on consecutive days.
- If you log a positive OPK test result that causes your fertile window to shift to a different cycle, the Fitbit app can’t provide an estimated fertile window.
For more information about ovulation predictor kits, see our blog post: Using Ovulation Predictor Kits to Help You Get Pregnant? Here's What You Need to Know.
Your estimated fertile window automatically adjusts based on the menstrual cycle data you enter. You can’t edit fertile windows.
To turn off fertility predictions, see How do I edit my menstrual health settings?

Why can't I log or edit a period or menstrual 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 menstrual health tracking calendar, see How do I read the menstrual health tracking calendar in the Fitbit app?
To turn off predicted periods, see How do I edit my menstrual health settings?

Turn on period notifications to receive reminders about your upcoming predicted periods.

For more information about turning notifications on or off, see How do I edit my menstrual health settings?
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:
- From the Today tab
- Tap the settings icon
- Tap Period Length or Cycle Length and adjust the number.
- Confirm your changes.
The icon shown on the menstrual health tile in the Fitbit app changes depending on where you are in your current cycle.
| Image | Meaning |
|---|---|
| If you haven't logged any periods or you aren't using predictions, you see the menstrual health tile with no cycle information. Read the cycle ring (the outer circle) clockwise. The dot on the cycle ring shows where you are in your cycle and that you are approaching your predicted period. It represents your cycle. | |
| When the dot is in the pink section, that indicates you’re on your period. | |
| When the dot is in the blue section, it indicates you’re within your estimated fertile window. | |
|
When the dot is in the gray section, that means you’re neither on your period nor on your estimated fertile window. |
To turn on period predictions:
- From the Today tab
- Scroll down to “Predictions, and then turn on both options: show period predictions and show predicted fertility.
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 How do I read the menstrual health tracking calendar in the Fitbit app? for details.
