Was my tech wrong at 15 weeks 3 days?...

I got my ultrasound done at 15 weeks 3 days and flew home and had a gender reveal at 16 weeks 3 days and it’s a boy! But I’ve read a couple of stories on here recently where they were told boy and it actually ended up being a girl. I’m nervous because I bought boy clothes already lol but not gonna lie when I first saw the ultrasound of my baby’s genitals I was a little shocked.. lol my mom was told I was a boy early on and then the next visit they told her I was actually a girl & yep they were right the second time because I’m definitely a girl lol what do you truly believe from my ultrasounds? (Btw the baby was peeing in the second and third pic😂)
