First day testing blood sugar

Since my apt was at 10 I only had to test lunch and dinner today. My lunch was a yummy DBL DBL from in N out with the buns. My dr want me to test an hour after meals and be under 120. Under 90 for fasting. Well lunch put me at 102. Dinner I had two servings of pasta noodles with Italian dressing, olives, and green beans. My test read 89. So far so good, but I'm concerned the numbers were low-ish. I've never had GD before so I don't know much about it all. If you had/have experience with GD, do the numbers look right? I just expected them to be a bit higher because I have GD. Any insight or advice is welcome of course :) thanks in advance.
