15 week gender ultrasound

We just had our gender ultrasound at a private ultrasound place. They were very good and patient with my little one. The baby kept crossing his legs. The tech said she knew pretty quickly but wanted to get a clear picture. I kind of spotted it right away too. Its a boy!!!!!!!

But just to calm my anxious nerves, what do you guys think? Agree or disagree? I keep thinking “what if its the umbilical cord?!!!” Lol. The tech seemed pretty confident though
