It has been a long time since I had a free trial and things may have changed since then, but I remember getting lost on the site and finding it difficult to work out how to cancel. I was sure this was done intentionally - easy to sign up/difficult to cancel.
In the end I rang the USA from Australia, to make sure I had cancelled the trial. As I was worried about ensuring that I was cancelling in time, I actually began the cancellation process a few days before the due date. But I was a bit miffed when my trial was cancelled immediately after I rang them even though I still had three days of the free trial remaining.
I have also had a couple of lots of Month subscriptions. To avoid any mixups I would advise you to take the 14 day free trial first. Then cancel it. Wait a day or two to make sure that your cancellation has gone through, and you no longer have a access, then just sign up for a month's subscription. If you only pay for a month, you will only get access for a month. At least I think that is the case?
Keep in mind that Find My Past also offers a 14 day free trial, though I haven't taken that up so can't advise on any details.
You may also be able to take advantage of a second, or more, 14 day free trials if you have access to another credit card and/or email address. I did this a while back. Someone may know if it is still possible to do this.
