Has anyone "stopped trying" and that's what finally did it?

Been TTC for a year and some change. Almost all of my friends where I live (I'm an army wife so I have back home friends and post friends lol) have kids. I ask them how long it took them to have kids bc almost all of them intentionally had kids, no surprise babies. Each one said it didn't happen until they "stopped trying" I was wondering if anyone else out there had that happen? Stopped tracking, stopped testing and just lived normally, and ended up pregnant shortly after?
