7 days free trial

check your account, https://account.adobe.com 

does it show all subscriptions and trials have been cancelled?

If your 7-day free trial started on the 8th and shows an end date of the 15th, it usually means your trial is scheduled to end on that date, but the exact time can depend on Adobe’s billing terms and your subscription details. I’d recommend checking your Adobe account’s plan page to confirm the precise expiration time. If you don’t want to be charged, cancel before the trial ends and check the confirmation message to make sure the cancellation went through.

Some hours here and there how does that matter. Don’t base your work on that, if you intend to use just the free trial get your work done sooner. Also, do mind to cancel the plan explicitly else you will be charged. See the refund rules for more details
