A member asked:
On 7&half we tvs shows 2 yolk sac, one with cardiac activity, other is empty. crl is 1.13 cm. is possibility of chromosomal abnormality ?

Always possible: The transvaginal ultrasound at 7.5 weeks does not rule in or out a chromosomal abnormality. It is believed that there are a lot more twins conceived than born and one twin just dies very early and this may be the cause of some first trimester bleeding. Only with early ultrasounds are we finding these 'vanishing twins'. This may be the case with your empty yolk sac. The other twin is usually normal

May be: Your obstetrician would be more valuable in discussing those findings and recommend what to do next, take care
