Urgent help needed regarding sexing please

Knowing my luck I collected my 3 "girls" this morning and now i am convinced one of them is a boy :( they are short of 6 weeks and I read they become fertile at 4 weeks? I have looked them over and one of the mice has a noticeable "lump" in the private area which the other 2 does not. I have tried to take some photographs but it wasnt very easy. hopefully someone here will be able to see what gender they are.

mouse 1 doe?

mouse 2 doe?

    First is safely a girl, unsure on second from that photo. Agree that third looks like a buck I'm sorry to say.

    Do you have a vet, or mouse breeder/owner nearby that can help you?

    Thank you for your quick replies and I'm sorry i only realised now that I've put this in the wrong section. I contacted the lady I got them off and she was really helpful. She has took them back and separated the buck from the females. They're on pregnancy watch now and if they haven't popped in 4-5 weeks I'll take the 2 girls back. Such a shame this happened but at least I'm happy I did double check their gender, I could have been in for quite a surprise otherwise :/

    I agree with the others... the gestation period for mice is around 3 weeks so you should know within that time. I'm so sorry that this has happened although it is sadly very common :(
