I missed my patch application window and now I can't start the patch, what can I do?

Your patch can only be activated within the calculated patch application window, which is before the start of your fertile days. If you missed these days and applied the patch later than instructed by the app, you can shift your patch application window by up to three days using the luteal phase adjustment. You can find out more about this in this article. If you are unsure about this, please contact our technical support (either directly in the app via "Contact support or via email: [e-mail]).

Note: Manipulating the patch application dates can have a negative impact on the reliability of femSense.
