Pls help me with this prediction!!

HI ALL!! Hoping you can help me with this explanation and give me a ramzi guess! I would be sooo appreciative. I'm trying to understand the gender experts girl prediction. This is transvaginal (6 weeks, 6 days), attaching ultrasound below! This looks boy to me, but they said they predict girl because the picture seems rotated and the bottom left of screen is my left. Can you please help me?! This is our 3rd baby, 2 boys at home so I'm SUPER curious!!
