Gestational Diabetes?

Breana • Had my rainbow on 12.4.19 💕🌈 Miscarried 12.14.18 👼🏼

So I’m about 9 and half weeks and got blood taken at 8 1/2 to check for anemia and thyroid, (which came back fine) because if I skip a meal just by a short amount of time, my blood sugar drops so bad I feel like I can’t move! How early can GD be tested for? I know I’m not eating enough right now because of my food aversions but it’s killing me especially if I don’t have a chance to eat while I’m at work!
