Live foetus and an empty sac at 12w5d What is the chance of the empty sac developing?

At 12 weeks and 5 days, the presence of a live fetus alongside an empty gestational sac typically indicates a situation where the sac has not developed properly. The chance of the empty sac developing further is quite low, as it usually suggests a missed miscarriage or abnormal development. In such cases, the body often reabsorbs the empty sac over time. It's essential to consult with a healthcare provider for a more accurate assessment and to discuss potential next steps.
