We had a viability scan today and according to the flo app and that working out my dates It showed I should be 9 weeks, they asked us could are dates be wrong but we know when we did it and the dates can't be out by almost 3 weeks as they are saying the yolk is only measuring 5 weeks 6 days, the second sack that is present is showing nothing but the sack is 20mm wide where as the one with the yolk is alot smaller.. I think they said about 9. We have now been referred to the hospital but our minds are in overdrive, I think we suspect that it stopped growing. Has people experienced this?
