Gestational diebetes at 30 weeks pregnancy?

I am now 37 weeks and was diagnosed with gestational diabetes around the same time as you did. Being on a strict diet and also seeing a nutritionist will definitely help to keep you within your limits. The doctor should give you some time to control the GD with diet but as you go on through the pregnancy, the baby will need to gain more weight/fat. This can sometimes make it difficult to control your blood sugar and you may have to make even more changes to your diet. If it can't be controlled with diet the next step will be a pill called Glyburide which will normally be taken twice a day, if that doesn't work THEN insulin is an option. But honestly you really sound like you will give it your all to stay healthy and do what's best for your baby. So don't worry, just limit your carbs and you should be fine.
