How many weeks do you have to be for the ultrasound to finally see the baby inside the sac cause right now its and empty sac?

Typically, a gestational sac can be seen on an ultrasound around 4 to 5 weeks of pregnancy. However, it may take until about 6 weeks for a healthcare provider to reliably see the developing embryo within the sac. If you are seeing an empty sac at this stage, it might just be too early, and follow-up ultrasounds are often recommended to monitor the situation. Always consult your healthcare provider for personalized guidance.
