Not enough fetal DNA for NIPT test

My doctor office just let me know that there was not enough fetal DNA for my NIPT results so basically they want me to redraw them . I was tested at 12 weeks so wasn’t too early . Im at work when I found out and I just cried at my desk cause I’m worried something is wrong . I have been waiting for my results and wondered why they took so long. They want to redraw but now I’m hesitant because what’s going to change if they draw them again … I have anxiety.
