Gestational diabetes while underweight

Hi,

I had GD with my first pregnancy 3 years ago and really struggled to get enough to eat (when I was already underweight). I was diet controlled + insulin.

I’m now 8 weeks with my second baby and the doctor did an initial sugar test and said it was a bit high. She said not to worry too much yet (and that I won’t necessarily get GD again) but to start to think about cutting down a bit on carbs and sugars. I am currently 44kg and was trying to build myself up for the pregnancy, so now don’t know how that’s going to happen!

Is anyone going through something similar and have any tips on how to control sugars without losing nutrition and weight?
