Help with Gestational Diabetes

sleeps

This morning I got a phone call from my doctors office saying I needed to come in for the 3 hour glucose test because when I took the one hour test my levels came back kind of high she said. This has really stressed me out. I can’t even remember if I ate or drank anything before I came in because I wasn’t aware I was even doing the test that morning. I am not one to take medications for anything unless I absolutely have to. So with that being said I was wondering what kind of diet I should adopt to help with this process Incase my 3 hour test comes back positive for GD? Everything has always been good at past check ups, I’m now 28 weeks so I’m really shocked and disappointed and scared. Open to any and all advice! I just really would like to care for this without insulin or pills if I can.
