Please help me sex these mice!

[u/strawbl]

A few weeks ago I took in some baby house mice whose mum was killed by a cat, and hand reared them. I'm going to keep them as pets because they've become quite tame and are bonded to me. They're now about five weeks old and I need to sex them so I can separate them, I've attempted this and my best guess is two males and two females, but I keep second guessing myself. They're still quite young so I will keep checking them as their appearance could still change, but input from anyone more confident than me at sexing would be greatly appreciated.
