I don’t understand Ramzi!

Can someone please explain it to me? I found myself down the internet rabbit hole the other day and nothing I read made it easy for me to figure out my ultrasound. I had a transvaginal done at 8w3d. We’re actually not finding out the gender until birth, but I wanted to test out the theory. 🤷🏼‍♀️

Based on the Ramzi theory, what should this be? The circled part is where the US tech said she believed the placenta had attached.
