How good at sexing are you? If you're not very experienced with popping I would try to get someone that is pretty experienced at it to confirm all girls. It's not impossible that you got 5 out of 5 female but it is unlikely and it's much easier to miss-sex a male as a female if you're worried about hurting them and don't apply enough pressure. I have no idea how you could miss-sex a female as a male though, once you see hemipenes, it's definitely a male lol.
