Three hour glucose test question please answer🤔

So I failed my one hour by three points it was supposed to be below 140 but I got a 143. So of course I am having to take the three hour test, I plan to take it tomorrow which I completely forgot about and I just ate two chocolate bars today. (terrible I know but somebody bought them for me) do y’all think those two chocolate bars will affect my glucose test tomorrow morning? Am I supposed to not eat past 12 tonight? Any tips?

I honestly feel so guilty that I ate two chocolate bars
