Dr appt today

I know with gestational diabetes the babies tend to run bigger i didn’t expect to have this big of a baby yet and it breaks my heart. On my 31 week ultrasound sound my baby girl was weighing at 4 lb and 10 oz. Today at my 34 week ultrasound she’s weighing 7 lbs and 5 oz, my second pregnancy i had a csection at 39 to a healthy 7lb 9.5 oz baby girl never in a million years did i think id have that in my womb now and to top it off her femur alone is measuring in the 96% percentile when babies should be in the 50-60% range. I was supposed to have a vbac but that is completely out of the question no matter what (due to history) i was extremely heartbroken today at the news. My dr doesnt even want me to make it to 39 weeks. She wants her out by 37 weeks as she could be 9-11 lbs by then. This has definitely been the hardest pregnancy ive had so far. Anyone going through something like this?
