I have to retake the glucose test wtfđŸ˜€

Im 30 weeks pregnant. I just took the damn blood test 2 weeks ago and never got a call back so today for my appointment i asked if my results came in good and it turns out they put a question mark and i think it said unidentified đŸ€ŹđŸ˜Ąwtf does that even mean? Now i have to retake it this friday and i dont want too AGAIN!!!! how does it say a question mark?!!!!! Im furious

Anyone else had to retake it because it said “?” Or “unexplained” ?
