Hey , I'm literally in the same as you I'm on holiday right now it's been 1 week and so far my teeth haven't moved so I think you should be okay , I made a post too all the peoples said , your teeth might move how much can't be said however another person said they should only move a bit ( this isn't if your on holiday for 2 weeks like I am ) but if you just go home and put your retainers on it should be tight and hurt but it will b okay and if your teeth have only moved a slight bit the retainer should put it back to normal . I hope that helped
