You should mention to doctor when you see them it's better to regulate now since it can cause development issues. I was diabetic before pregnancy so I had to follow a strict diet while pregnant and check my sugars on a regular basis.
I had diabetes while pregnant with my first and I didn't feel anything ... I just had to check my sugar 4 times a day . I didn't drank soda, juice, no candy, no sweets. Etc and my son is healthy . Good luck
