Daily blood sugar monitoring for gestational diabetes

I had gestational diabetes with my first child. I'm 12 weeks with my second and my dr. hasn't ordered me to have the test yet. But I decided to use my daily tester to see what happened after I had dinner tonight. What is the normal range again? You take the test right before a meal, and then 1 hour afterward right? Before it was 77 and after it was 130. Is that too high? Also, is the result any different on your arm than your finger? I tested with my finger tonight because I couldn't get enough blood from my arm.
