I just went to my 36 week appt , I am scheduled for a csection 3 weeks from today my dr was a little concerned because my baby is measuring 3 weeks bigger than he should be , he checked my blood pressure and it was normal and than just told me that my csection will still be when I am 39 weeks.

My first born was a 8lb baby so idk if I should be concerned that he is measuring 3 weeks ahead and should have let the dr know that he got me feeling worried or it’s just something normal ? I just don’t want to have complications on the day of delivery.
