SBR gives you a 1 month notice when you PRO will expire. If you renew early in that 1 month window your PRO will still expire at the end of your term. SO I would think that your PRO will still expire in August if you renew today.
Your expiration will still be in August, the next year. It doesn't matter if you apply 1 month prior to your pro expiration as the status will still expire on the last day of your last subscription and not on the day were you applied the status.
