I went and had a private ultrasound done yesterday well the baby wouldn't corporate and had its legs closed ultrasound tech said she was 99% sure it was a girl but she said I can go back next Friday for free so she can be a 100% sure she said this early girls have swollen labia she said when baby closed legs real tight she could see something very little but when baby opened legs up she couldn't see anything but said that could be the swollen labia and she said if it was a wee wee it would be longer and she didn't see any balls lol has this happened to any of you ladies and when you went back the gender be different than what the tech told you
