Any ultrasound gender experts on here?

Baby is measuring 13w 4 days here

It’s said that 13w is 100% accurate via ultrasound and she only did the ultrasound for me at 13w.

Do I trust the ultrasound tech? Lol I just don’t know what I’m looking at😂 I was like this with my 1st pregnancy, I had no clue what I was looking at as well. The tech was correct though 😂
