Hello @Marcellalyons11. Welcome to the community forums! 

Thank you very much for the detailed information. At this time, I'd recommend trying to charge your Charge 3 and if it refuses to charge, please follow the steps suggested in this help article: Why isn't my Fitbit device's battery charging?

If that doesn't work, please try to perform a long restart by following the steps below: 

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.

On a side note, I've moved your post to the Other Charge Trackers board to keep our forums organized. 

Hope this helps.
