[|Human|] hi gud evening.im  9 week pregnant and finaly have ultrasound my doctor said that may yolk sac is bigger than the embryo the size of my yolk sac is .70cm and the embryo is .19cm no heartbit.please answer me what happend to my baby is he or she safe?
[|AI|]  Hi, Presence of embryo is a positive finding, usually we expect a heart beat to be seen once embryo size is 7 mm. So it would be best to repeat scan after 10 days and check for heart beat. Yolk sac more than 5 mm are known to be associated with miscarriage, so I would advise you to have a regular ultrasound scan to track the growth of the embryo.Also, I would like to ask you, are you sure of your dates and do you have a regular cycle? As usually fetal heart should be present by 7 weeks. But it's possible that the conception occurred later or cycles are not regular. Only a repeat scan after 10 days of this scan, will tell us about the growth and prognosis. Hope this helps. Regards.
