Passport expiration date

I'm landing in BKK on November 11 and flying back on November 23. I'm from the visa exempt country and could stay in Thailand for 30 days (or so I understand). My passport expires on May 25 ie 6 months and 1 day after sechedule departure date. Could I have any trouble with that? For instance because in theory I could prolong my stay until December 10 that is less than 6 months till my passport expires.
