@CertifiedFresh As long as the billing information on your Google Play is up to date, your trial will successfully renew when it is up.
When that time comes, the card you have on file with Google Play will be charged automatically, and your trial will revert to a monthly subscription.
If you'd like to update your payment information, you will need to do this directly with them. Click here to visit Google's help page with information on how to manage your payment options on your Google Play account.
Hope this helps!
