My aligners feel loose (day 3)?

The first few days were excruciating...and this morning had me feeling mildly grumpy. I took my aligners off at work a few hours ago, ate, and put them back in...but now the top aligner feels loose? I feel like I have to suck the saliva out of them because they don't feel airtight anymore and spit is pooling in them. I've tried pressing them in tighter with the chewies but it isn't working..do I really have to go the next week and a half sucking spit out of this loose aligner?
