Measuring bigger


Ok so I’m currently 35+4 weeks pregnant and due on the 18th of December. My obstetrician was concerned with the tape measurements so I had an ultrasound done.

Baby is definitely measuring 2-3 weeks ahead. And estimated weight is 3.1 kg. I have an appointment in 3 days with my obstetrician again.

So does this mean I’m 37-38 weeks pregnant? Had anyone else experienced this in their pregnancy? And if so what happened next?
