Can you ladies help me understand this?

So at 6weeks pregnant I was admitted to the hospital and my hch levels were 300,000, so I was non stop throwing up. It was miserable. The doctor performed an ultrasound and gave this picture but did not say anything. Waiting for my actual OB to see. My mom said maybe twins in the same sack? Those two white dots with arrows are what’s got us thinking twins. Thank you so much for your time. 💜🥺
