I found out I was pregnant at over 20 weeks. First scan by my dates was at 21+2 but they put me at 20+6 based on HC, other measurements were ahead. At my last birth the surgeon said I absolutely cannot go beyond 39 weeks.
How accurate will their dating have been at that stage? Wondering if I should push to have the due date bought forward inline with my dates otherwise I may go beyond 39 weeks.
