Hi there @HugoDog, welcome to the Community Forums. Thanks for the steps you've tried so far. 

Before anything else, please make sure that the Fitbit app is updated in your phone. Then, I'd recommend to try the following steps:

1. Close the Fitbit app from the open apps, and reboot your phone.
2. Open the Fitbit app, and tap on the Female health tile from the Today tab.
3. Tap on the gear icon at the upper right corner.
4. Search for the "Edit Setup Values" and tap on "Cycle length".
5. Enter the correct number of days, and then tap on "Done" or "OK".

If the same keeps happening, please provide me with a screenshot of what is displayed in the Fitbit app. For instructions to attach a picture, check this post.

I'll be here, keep me in the loop.
