You can sync your subscription with your cycle by changing the frequency of your orders.
Log into your account and go to "Your subscription".
In the “frequency of deliveries” section, you can change your delivery to arrive when you need (between every 3-8 weeks).
Click the ‘change frequency’ button and select from the drop-down how often you would like to receive your tampons. Don’t forget to save your new frequency, and all of your future delivery dates will be amended accordingly.
