Two days ago I had an NHS scan at 6+3 according to LMP, though we only DTD once that cycle, giving a five day window for conception. If work back 14 days from those 5 days to get a 28 day cycle LMP date, Id have been between 5+2 - 6+0
The results were a sac with a mean diameter of 5.7mm which dates at 5+0
A fetal pole of 4mm which dates at 5+6
No heartbeat seen.
History of recurrent loss.
From what I gather CRL of >5mm without HB is worrisome, but
