6/7 week ultrasound

anyone else’s look this way? I’ve never seen one look this way. Usually it’s a clear shot of a yolk sac and a raisin sized blob but mine is all globbed together..Doctor couldn’t say whether this was baby and yolk sac. Does anyone know what the tail” looking thing that reaches across the sac? I’m about 6/7 weeks. Hcg levels on the 1st were 1000 something, on the 7th they were 3838. Hoping all is well. ❤️
