Glucose test - Waiting and wondering

I’ve done the 1 hour glucose test 6 times now in my life and I’ve never failed it. I did have to repeat a 1 hour once bc I forgot I was taking it and I didn’t eat accordingly (aka I ate 3 big ol’ cookies 30 minutes before). Those of you that have failed it, could you feel it in your body that you weren’t handling the sugar well? Like did you feel wired with the drink and just have a feeling you failed? Just wondering if I’ll fail and not know. I drank the drink and am waiting for my blood draw thinking “Whew I’m ready to get this over with!” But would I kind of know if I’m failing it? Anyway, thanks ladies! ❤️
