PZ - I agree with Heather. Stick to your normal diet. You're eating healthily anyway. I know you're afraid of losing the homebirth, but try not to focus on that.

I did my 2 hour test at 26 weeks and was fine. I was eating healthily, but didn't have a perfect diet. A friend did it at the same time. It's suspected she should have done it at 28 weeks, as it's likely she developed late GD.

Her bub came 3-4 weeks early, was very big with poor blood sugars and slow response and ended up in the nursery for 10 days. He did not look well in his photos. They realised his mum probably had GD.

I know it's not the case for all GD bubs, but there's a good reason for them to be born in a hospital and close to a SCU/NICU. Some of them can be very sick.

I don't mean to scare you. I just want you to focus on keeping your diet healthy. Don't try to 'trick' the test. You really do want to know for bub's sake if you have GD or not.

btw - I have family with Type 2 diabetes and i was fine despite being overweight.
