Failed the 1 hour glucose test

So a couple of weeks ago I failed the 1 hour glucose test and yesterday I took the three hour one. Definitely happy to say I passed the three hour. The only reason I failed the one hour was before they told me I could eat before coming and I did and it messed everything up. Then the nurse argued with me that eating doesn’t effect anything she also told my carbohydrates do not turn into glucose sugar. She didn’t even tell me to fast this time around either but I did it anyways. Very annoyed with my OB’s office.
