DH thought it was a boy for most of the pregnancy. (I waffled a lot!
) But we had an u/s at 21 weeks that said girl. She had her legs spread and we got a really good picture from below showing the "three lines."
This thread got me really scared that I would end up with a daughter with a penis! But I just had another u/s at 32 weeks. We asked the tech to confirm the sex. Wow! At 32 weeks a baby's genitals really are fully formed!! We could see all the details of the vulva. This is NOT A BOY!
Maybe some of the people who were told the wrong sex had an inexperienced u/s tech, or the baby wasn't being cooperative enough to get a clear shot, or maybe it was an earlier u/s. (My little girl is a shameless hussy and had no problem showing us her goods!)
