Bump measurement at 28 weeks??

So I'm under a consult and getting growth scans from 30 weeks but had my 28 week appointment today. Midwife measured me and said I'm 32cm. She kinda pulled a shocked face and I laughed and said is that big and she was like you're getting an ultrasound in 2 weeks so I'll have to see you after that and well have more of an idea. I had a scheduled section with my first (he was breech) I want to try a natural birth but been told if baby is big I will have to have a section. My son was only 7lbs 10oz. What did your bumps measure at 28 weeks??
