I am 32 weeks pregnant and I have gestational diabetes. It isn't so bad I was so overwhelmed at first but once I talked to my nutritionist made it a lot easier. Basically you just have to watch your carbs (don't worry so much about sugars) and limit your self to 45g of carbs at meal time (breakfast lunch dinner) hopefully they have you meeting with a nutritionist to give you meal ideas and tell you what food is considered free food (food you can have unlimited) which will make it easier to cook and you won't feel like you are starving! Hope this helps some!
Not me personally but a few mums in the social pregnancy forum have gestational diabetes
