Looks a lot like mine did at 17 weeks and I was told boy too. Congratulations!
I'm hoping to get mine confirmed again at my anatomy scan next week, because I've already bought boy clothes. I can't help worrying that it might have been something else making it look that way too. Like maybe it was too early and it was just swollen girl parts, or a hand in the way or umbilical cord etc, haha. So I know how you feel!
