5w5d ultrasound abnormal?

Sabrina

Guys I need help. I was looking at other ultrasounds and they look so different from mine. Is this abnormal? Why don’t I have a clear white ring for the yolk sac or do you see it at the top? Doc wasn’t sure if that was the embryo no heartbeat and I’m nervous the pregnancy isn’t going as it should despite my symptoms growing. Please help has anyone had this kind of ultrasound at end of 5w??
