I went for my first scan at 17 weeks and both me and my ob saw a girl (I have two boys already so I think I would know) went for my anatomy scan at 21 weeks and was told a boy by ultrasound tech but we know the baby had the umbilical Cord wrapped around leg and at one point legs were crossed I believe when baby opened legs the umbilical cord was right in the middle. What do you think ? Last picture is potty shot of my first son (all ultrasound were done at same hospital) I think there is a huge difference in penis size and potty shots are on two different sides.
