Anyone have insight into if you can workout before taking the 1 hour glucose test?

I'm 29W, haven't worked out in 2 weeks because my schedule hasn't aligned with my spin studio's schedule, but I finally got in tomorrow at 5:30 AM. My doc did say I could eat before (she recommended toast). So, I was going to work out at 5:30, eat around 6:30, then test around 8:00.
