12 week gender determination test that tech gave?

Alexandria

So when I went for my 12 week sono, the tech asked me if I wanted to know what she thought I was having. I said sure lol. She said because the spine was 55 degrees parallel to the baby’s head or something that she thought I was having a girl...so I was confused because I never heard of this determining method before and I asked my friend who’s a tech and she had never heard of that before so she asked one of her tech friends who said it’s some new test they can do to try to determine the baby’s sex but she would never determine the sex by that test. Has anyone else ever heard of this and if you have, was it accurate? My husband and I have a sono on Friday to see the baby’s sex. I’m now 18 weeks and will be close to 19 on Friday.

UPDATE: Well the tech was right lol...6 months pregnant with my second baby girl 🤰🏾🤷🏾‍♀️😂👶🏾❤️
