Failed 1 hour glucose test

So yesterday I had my one hour glucose test. I failed I needed to be at 130 or under and I was at 153. I didn’t fast for it at all and the worst part is that I did mine at 5 PM. So now I have to do the 3hr test. Has this happened to anybody? I’m really nervous about it and I really don’t want to have gestational diabetes. Any advice appreciated.
