I was 16 weeks and found out I had GD, my baby measures 2 weeks bigger, I also have more amniotic fluid around the baby, so it all depends on the person cause everything affects people differently...I'm currently 38 weeks
I found out a few days ago that I to have a gestational diabetes :( I'm 29 weeks ! I've heard that if you maintain a healthy diet and exercise then the baby's weight should not be affected .. have you gone to a diabetic educator yet ?
