Chance of being wrong?

Chelsea

I was 22 weeks 3 days on Saturday when I had my anatomy scan. The tech said it wasn't the best picture, but pointed out the three white lines and said that means girl and saw no parts looking like a boy and that her professional opinion is a girl. Could she be wrong? Would a boy part be obvious this far in the pregnancy?

Here's a profile pic for fun. (Sadly she didn't print the pic that showed girl)

Update: I had another scan on Monday at 27 weeks and 5 days because they couldn't get good images of her spine at previous ultrasounds and the tech did double check that my little been was a girl and is definitely a girl! Thank you to all responded! 💕
