I'm 24 and have an overwhelming urge to have a baby. Looking for advice about what to do

So I'm 24, my boyfriend is 25. We have been together for about a year and I came to live with and travel with him. This urge to have a baby has been there since I was 21 and has slowly and surely crept up on me. Sometimes it is so overwhelming that I feel like breaking down.

I want children. This is definite. My boyfriend is a bit more shakey. He wants kids, but not definitely not yet and probably wants to adopt. I agree with him. I'm 24, I want to enjoy my relationship and grow with him and, logically, I feel like I have plenty of time to enjoy my twenties. There are things I have left to achieve, places I want to see, basically enjoy my freedom. But it is getting swamped by irrational, overwhelming desire to have children. And I don't know what to do, I feel like I would regret it if I chucked my relationship to pursue baby making at this time.

Does anyone have any advice?
