Ramzi theory this one please! :) Boy or girl?

First pic 6w, 6 days via Vaginal ultrasound, hr 165. Second ultrasound was supposed to be 10wks but they bumped us to 11wks, via abdominal, hr 165. Please include your thoughts or theories as to why. I'm obviously new to the theory, it's my first! ❤️ Btw baby laying face down in last ultrasound, they flipped the image.
