I'm 26 weeks with my third and I am measuring 30 weeks. The doctor said it could be due to diabetes. I did my glucose test today and find out the results Monday. I go back in two weeks for a growth ultrasound and appointment. My question is; has this ever happened to anyone else? Was it due to diabetes? What was the outcome? I feel awful...like I've failed my baby. I've also gained a lot of weight. I gained 9 pounds in just one month for a total of 20 pounds in 26 weeks. :(
