has anyone asked to do the GD test early?

To

So I have a few of the risk factors. Overweight, I had it during my first pregnancy, and I'm on Makena. I haven't felt well the past week and it seems to be related to food. I felt my sugar drop today and almost passed out. Has anyone ever asked to do the test early? I have an appointment on Friday and I'm debating asking. I'm not supposed to take it for another 6 weeks. I'm 22+2 today.
