Carb intake

Has anybody’s provider been concerned about too low of carb intake?? I am 27 weeks and my provider wants me to keep a food log because she is concerned about me eating too little carbs for the baby’s needs. This is my second pregnancy and I am well aware of the recommended carb intake for meals and snacks but I don’t think I should be required to log every last carb that I eat🙄 I will be starting bedtime insulin to control my fasting readings but do not want to go on mealtime insulin!
