Failed glucose test

I went in for my one hour glucose test and just heard back that I my number was elevated. She said she likes see it below 130 and mine was 140. I am wondering if it has anything to do with Mother's Day being the day before the test and I ate a lot of sweets?? Now I have to go back for a three hour test. With my first son I had no problems with my glucose level so I am just worried. Did anyone else go threw this??
