Hi, I am prediabetic, and just found out that I am 5 weeks pregnant. I took a sugar level test at at fair yesterday, just for fun, and I was shock to find out that it was 162! I start dieting right away, and I will see a doctor very soon. Should I be concerned? Is there a chance I can lose the baby because of that. I am also 45 years old. I have a 30 months old baby, and I developed gestational diabetes during first pregnancy.
