Can't edit a period since the pencil has disappeared

[RainaR]

My periods arrived 2 days earlier from predicted. My pencil icon disappeared 11 days before my predicted period. I’m unable to log details correctly now.

Welcome on board @RainaR, it's nice to see a new member around!  If you're having difficulty doing this, please close and then restart the app. Also worth noting that you should have the latest version of the Fitbit app downloaded. 

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.
• A period must be less than 11 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.

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.
