Twins?

I posted this in general pregnancy already I’m just looking to get some more feed back from some twin moms or anyone with experience in ultrasounds. This was a super quick ultrasound. It lasted approximately 1 minute the tech didn’t look around what she landed on when the probe went in was what she took a picture of. She claims the structure to the right is the yolk sac. I’m not convinced... any comment would be appreciated 😊 this is baby number two and my first looked nothing like this one!
