gestational diabetes question...

Even if I can have 30 carbs in the morning do I have to eat them? I had 2 eggs (0) boost glucose controlled shake (16) boca burger (5) and 1 tbsp of 75% reduced sugar ketchup (1) which equals 22 and I'm super full. New to this and don't have my class till July 10th. Thanks ladies! Went grocery shopping and got tons of carb friendly foods!
