I had a scan at epu yesterday where the gs was 18mm and embryo 5.5mm. I then had a private scan today which was booked in advance with a consultant obstetrician where the measurements were 14mm for gs and 9.3mm for embryo. I’m so confused. The latter scan puts me in the gs-embryo ratio danger zone for miscarriage so I need to go back in 2 weeks for another scan. Has anyone had experience with a similar situation? Can the measurements both be accurate and the baby has grown that much but gs has shrunk?
