Gestational diabetes

Angel
Well I went for my 1 hour test today and my blood sugar was 225. My doctor put me on a diet and he is going to check my blood sugar again in 2 weeks. I never had this with my son. I don't really understand it. I thought women who had gestational diabetes gained a lot of weight. I have only gained 8 lbs and I am 27 weeks. I weigh 141 now and am not overweight. Anyone else dealing with this? Any ideas about what I can eat? My doctor said I can only have protein and vegetables. He said I couldn't even have fruit but I have been researching and it says that I can have certain fruits. I'm so confused!
