Hemoglobin A1c levels

Amnesty • Mommy to Aurora born at 31w2d, Declan born at 37w0d and Connor and Liam due 1/31/2018.

So I am 10 weeks pregnant and my levels are already 5.6 according to the results I am in the prediabetic range. I have had gestational diabetes before but it was with my first child, this is my third and its the earliest anything has shown up. Anyone else have experience here? I don't really know what to do since I delivered almost right after my glucose test with my first. I have an appointment on Thursday but am slightly freaking out.
