Ramzi theory guesses?! Confused because of the yolk sac, help!

Am

I've been reading about the Ramzi theory but I think I'm just confusing myself because the yolk sac is also pictured 🤦🏼‍♀️ baby on the left, yolk sac on right. . Any guesses?

Transvaginal ultrasound at 7 weeks 5 days, HR is 139.

Thank you!!!! And congratulations to all the other expecting mamas! 💗
