Scared of incorrect gender!

So let me start off by saying I’m a FTM so I’m not used to seeing what the differences in ultrasounds are.. but am I the only one that’s terrified of learning the gender guess was wrong?!

I went to a ultrasound location that specifically tells you the babies gender at 14+ weeks and I basically went at 14w and a couple days.

I was told I’m having a boy, but could that be wrong? I’m so scared it’s incorrect after hearing so many stories about the tech being wrong on here!
