2nd baby, so assuming I have GD

Al

13+5 and having to start testing as I had GD with my first. Started at the hospital yesterday, so I’ve just done my fasting bloods. It’s frustrating because I’ve gone over by 0.1 (in the UK; I think we use a different measure). How do I control my fasting levels? Feeling depressed knowing there’s such a long way to go with this!

Also, only diet controlled at the moment! Thanks for any help - feeling very low.
