You can view your subscription details by clicking on your image in the upper-left hand corner of the page (when logged in). A user menu will appear. Click on "subscriptions" to view your subscription details. You can also click here to go directly to that page.
On your subscriptions page you will see the details of your current subscription, including when your subscription was initially created, the terms of your subscription, and when it's set to re-bill. Note that when you cancel a subscription it will still show as "active" until your current term expires.
