Hallow Dear, At 9 weeks gestational period if ultrasound shows gestational age of less than 5 weeks, it does draw attention. Moreover, the gestational sac is without foetal movements. At 9 weeks, foetal movements are definitely visualized. It is suggesting that the foetus is likely to be non-viable - missed abortion. Please repeat the ultrasonography after a week. If still it is not showing any cardiac activity, the diagnosis of missed abortion is confirmed. Then you will have to get the pregnancy terminated. It is not advisable to defer the termination of missed abortion for indefinite time since it may lead to some serious complications like severe bleeding due to clotting disorders (DIC) or infection. I hope you are convinced with the explanation.
