Is there really a "right time"?

My boyfriend and I have been entertaining the thought of having a baby recently. At first, I thought it was completely ridiculous that he would even bring it up because we aren't even married (we've both agreed that we want to want another year or so before we get married) but the more he talks about it, the more I start to believe he's right. He makes decent money at his job, enough to pay all of the bills in our apartment because I don't work. I'm a student but I do my schoolwork online. We still have money left over at the end of every week, even after bills come out. We'd have to either rent a bigger apartment or a house if we had a baby, because our apartment now is only one bedroom, plus the cost of baby stuff. I'd have to get a job while I was pregnant so I could save up money before the baby comes, which I wouldn't mind. This just isn't how I saw my life going a year ago. I always planned on getting married and THEN having kids. But I don't know. I think my boyfriend and I both really want this but I'm just not sure if we could actually handle it. Any advice?
