How soon into a relationship did you have kids?

I know there will probably be wildly varying answers, but I think my perspective on this is changing as I’m now over 30. When I was younger, I was adamant that I would want to be with a man for at least 3 years before I’d have children with him. As someone who’s single, 31 next month and ideally wants a first child by the age of 35, this is not looking like reality 😂

So I’m curious because I’ve heard that sometimes the older you get, the quicker some of these milestones can take place, I’d love to hear stories and opinions!
