Free Trial

>1 month trial

I don't know where you saw that, but everything I have read is that the trial is one week, not one month

When you 'click to agree' to the subscription terms while buying a subscription, that means that you really do need to read BEFORE you buy a subscription... https://www.adobe.com/legal/subscription-terms.html

no, usually free trials are for the first time period free and then automatically roll into a paid subscription.  if that was an annual subscription, there will be a cancellation fee* (for early cancellation).

check your account to see if you have a subscription, https://account.adobe.com

*if you're cancelling an annual plan early, there's a penalty (=1/2 the cost of the remaining months).
