Hi Cat don't be alarmed as stress will only make your levels higher. The same thing happened to me and like you I was scared but I went on to have a text book pregnancy & birth and my son was only 7lb 2oz so not everything they say is nessessarily correct just go with it and try not to worry too much! My gestational diabetes disappeared but type 2 came back to bite me on the bum 3 years ago so 3 years after I had my baby so my best advice would be to be as careful as you can afterwards to ward it off with a good low carb diet and exercise! Good luck with your baby and don't get too caught up in the diabetes and try to enjoy it still you'll be fine! Xx
