Definitely a girl?

I’ve been told 3 times now that little baby is a girl , with both my previous pregnancies I have had clear as day potty shots ( I have two boys ) and I am so happy to hear a girl I thought this baby was a girl from the beginning but still makes me anxious not getting the best look!

3rd scan below is 23 weeks

Second scan was 19 weeks , looks to me like maybe pointed to wrong area? The lines look more defining in the arrow area but I have no idea!

1st scan was 14 weeks very early I know but they said girl then as well!
