Has anyone had luck with this??

So my childhood bff and I want to try to get pregnant around the same time. Has anyone had luck with this?? Our dilemmas are that she isn't married and she want to be married first which I'm thinking will happen soon I have a feeling he's about to pop the question lol, and I personally haven't been able to get pregnant after five years of unprotected sex with my husband. We wanted to have kids before 30 and kind of wanted to try right after she gets married. Has anyone had luck with something similar like in a situation kind of or just like ours??
