Possibly Deined VBAC

Pregnant with my second and My doctor says I’m a good candidate for a VBAC my first was an emergency section at 39 weeks. But I recently had a growth scan baby’s is estimated to be 3 weeks ahead in size and if baby continues to grow at this rate. She suggests another csection if I dont go into labour before 39 weeks on my own due to the baby being to big and I have issues with blood flow to my uterus with caused complications with my son. Disappointed I hope I can try for a VBAC
