I failed my glucose test, need tips for 3hr test!

I did the 1hr glucose test on Thursday & then flew out to Chicago for the weekend for my baby shower where I indulged in our brunch menu of donuts, cake, fruit, etc! I’m back home & got the call today that the limit for normal is 140 & I tested around 150. I’m scheduled for the 3hr test tomorrow at 8am now. What I’m wondering: will my results be altered by my weekend ‘binge’ so to speak? Should I reschedule for Wednesday instead? I normally eat healthy salads, eggs, protein etc but since I was out of town I ate out every meal & not healthy! I just want the results to be accurate. Thanks!
