My doctor sent me a letter stating that she will be testing me for gestational diabetes at my next visit I am going to be 20weeks and 3 days. Is that normal that they test me at this time for gestational diabetes or do they think I am at a higher risk I am overweight but did not have it with eather of my children And diabetes does not run in the family at all. Also I only gained 5 pounds so far and Im 4 1/2 months pregnant. Please help me thanks
