I went for an optional gender scan today, only thing is my baby bean was not having it. Wouldn't stay still long enough for the sonographer to be 100% sure, but she said she thinks its a boy. she told me boys have a little circle, girls are 3 lines she got two brief looks and screen captures of what looked like a circle, but can't be 100% because the umbilical cord was very close to the area 😩 Going back Friday to hopefully know for sure. Has this happened to Anyone? Did what the tech suspected to see be accurate? Going crazyyyy here!!!
