First ultrasound...any guesses?

Kayla • Wife & mama raising two babes with my angel baby Ada in heaven. ✨ 10/3/2020 Rest In Peace my beautiful baby girl. 💖

This was my transvaginal ultrasound at 6w6d. Heartbeat was 140. I’ve never done the ramzi theory with my last pregnancies so I’m confused on how it works. I’m curious to see what you guys think!
