NEED HELP!!!!

Amanda

I had a 16 week scan today and was told we are having a girl. But she was talking about how the nub is straight with the spine so it's a girl. But other moms posted saying by 16 weeks their girls has no visible nub. So now I'm second guessing the tech and I'm confused. Anyone have any experience with this at the 16 week mark? Or any guesses? TIA!
