Had another ultrasound today n for the second time in a row the baby is measuring in almost 2 weeks ahead of my original due date not to mention it weights over a pound now. Based of my original due date it should weigh bout 10 oz keep in mind I have gensational diabetics.if I go off of the due date it's coming up with at ultrasound clinic my due date should be in March. Has then ever happened to anyone??
