are we ready?

My boyfriend and I were watching a movie last night and there was a pregnant women staring the scary movie. He had made a comment about how I would look great pregnant... I said what? He repeats himself and I asked we haven't really talked about me being pregnant. He says "well when I look at you, I see my future wife, and the mother of my children" I immediately blush because every girl wants to hear that. Today I had asked him when he sees himself having kids. (We have already decided we wanted to be married in 2 years at the latest and we don't want a big wedding or anything) I said I wouldn't mind waiting until after we get married. He said he really doesn't care. He has a good job and we have our own place with another room. He said if you wanted to have a baby right now I would be okay with it. He's always wanted kids. I recently found out a month ago I was able to have kids, after being told my whole life I would never be able to. So this whole conversation is really new to me. I mean is it that easy of a conversation? I feel like all my friends struggled when was ready to have a child. Most of them were teen parents. I'm 21. My sister and myself are the only ones without children. I feel like I'm joining the party late but then sometimes I feel like I'm still young.
