Hi all

I had my first scan done at 5 weeks 2 days (by LMP), and measured in at 5 weeks 1 day. My GP left my EDD as per my LMP.

I had another scan today which would put me at 7 weeks by LMP or 6 weeks 6 days by first scan date, but I came in measuring at 6 weeks 3 days.

We saw a heartbeat of 132bpm and CRL of 7.1mm. My gestational and yolk sacs were both measuring 7 weeks 4 days.

Based on this information, which should I take as my EDD? Which will the birth centre take as more accurate, the earliest scan or the one showing viability with a heartbeat?

TIA!
