Gestational diabetes diagnosed but baby weight and BMI normal

Hi, i was just diagnosed with gestational diabetes last week, now is week 28. My private gynae didnt mention to do finger prick, just say control carbs and sugar intake. Im worried how to monitor if dont finger prick and no dietician referred to as well. For GD, do we need to see endocrine doc? Any suggestions what i should do now besides eating healthy and exercise? Am quite worried.
