Period prediction is wrong

[Justalysn]

I will be keeping an eye on my period prediction and it will be spot on for the start day. Then when I'm sure my period is (finally) over, I'll go back in to edit the end date. At least four times that I can recall, when I go back in, the date it has for my period to start will have changed, often to the day I am reopening the app. I will then have to try to remember what day it started and edit the entire cycle, the beginning of which had previously been accurate and untouched. At this rate the predictor is turning out to be more work and less reliable than my old school method of winging it.

Hello there @Justalysn, welcome to the Community Forums. I'll be more than glad to help you out with your inquiry.

First of all, I'd like to mention that during your predicted period, you’re asked to confirm whether your period started. Tap or click Yes to confirm that your period started or Not Yet if it hasn’t started. Tap or click Edit to adjust the dates before you confirm your period. 

If you confirm a predicted period, the predicted period becomes a confirmed period. If you don’t confirm a predicted period, the prediction remains on your calendar. After the last day of the prediction window passes, the entire predicted period shifts to the next day. Note that the calendar doesn’t update until after midnight.  Initially, your predictions take into account the average cycle and period lengths you provide during setup. Log your period consistently to receive more accurate predictions.

Your estimated fertile window automatically adjusts based on the menstrual cycle data you enter. You can’t edit fertile windows at this time. You can swipe down to look for the date you want to edit and follow the steps below.

To add or edit a period: 

1. From the Fitbit app dashboard, tap or click the female health tile.
2. Tap or click the start date of a period on the calendar.
3. Tap or click the pencil icon to add or edit a period (you can also tap and hold a date on the calendar). If you turned on predictions, the entire period appears on the calendar based on your average period length.
4. On the calendar, tap the first or last day of a period and then slide your finger across the dates to adjust the period length. 
5. Tap or click Save.

To delete a period:

1. From the Fitbit app dashboard, tap or click the female health tile.
2. Tap or click a date on the calendar inside the period you want to delete. 
3. Tap or click the pencil icon.
4. Tap or click Delete.

If you have trouble adding or editing a period, see our troubleshooting tips.

Hope this helps, I'll be around if you need further assistance.

I don't have a delet button! There is no way for me to delete a period or correct a projected period. I can add one but I end up having the projected one and the actual period on the calendar

I am in the same boat I don't have a Delete Button at all.  Due to a Single day saying there is a PERIOD MY PREDICTIONS ARE ALL WRONG.
