I went for my 20 week scan yesterday to find out that my little she is a he. We did the NIPT (non-invasive prenatal test, similar to Harmony or Panorama, Matern21 etc)  and were told that the baby was a female at about 13 weeks, but in the scan yesterday there were very clear male genitals. She checked over and over because she, nor we had ever heard of this test being incorrect. Now I literally didn't sleep last night terrified that the test got something else wrong.
