I failed my 1 hour glucose test and now I have to go back and do the 3 hour test...

I normally worry about every test I’ve had to take, but failing this wasn’t even on my radar. I just assumed that because I’m almost under weight it wouldn’t even be an issue. Well now I know weight doesn’t always matter! I failed pretty bad too...180 when the cut off is 130. I’m really hoping it was a false negative, I wasn’t even thinking and had a Chick-fil-A milkshake a couple of hours before my test so I’m really hoping that’s what caused it. (Although, I feel like they should have warned me to fast or not have had super sugary foods! As a first time mom I just don’t have a clue 🙄)

Has anyone failed the 1 hour and had to take the 3 hour with such a bad number? What was the outcome?
