Diabetes

Anyone help me? Iv been tested for diabetes and haven't got it, every appointment I go to I have glucose in my wee, they can't send me for another test because I'm 32 weeks so they checked my sugar again and it's normal, I don't understand why I have glucose in my wee all the time and not have diabetes! Also I'm having a big baby! She weighed 5 pound 9 at 32 weeks the other day! I'm mortified!! They just can't tell me why the glucose is there and yes I am on the chubby side but not majorly
