My friend is in the wrong.

I don't really know what to do. My friend is trying so hard to get pregnant. Her boyfriend isn't ready yet.. She was telling me the other that when her bf pulls out n puts his cum on her stomach, that she scoops it with her fingers and sticks it inside of her when her bf walks away to grab a towel or whatever. They aren't even financially stable enough to have a baby. I'm good friends with both of them, but I'm not sure if I should keep my nose clean, or say something about it. Can she even get pregnant that way? Opinions please
