<human>: Can you provide a brief rundown of the text in within 3 sentences?

First off, let me start off by saying I KNOW we are young. I know it would not be smart to have a baby anytime soon. 

We talk about babies and having a family and names on a somewhat regular basis. We are getting married in a couple of months and I just can't shake this thought in my head lately. Everytime I try to bring up maybe wanting to know around when we might have a baby, my fiancé assures me it won't be a super long time and tells me everything will work out. I know he wants kids eventually too but I feel like this is something I want to be more comfortable knowing before we commit to each other. I don't really know if I should even bring it up again, or if I should even be thinking about this since I'm pretty young. What do you think r/relationships? I'm scared of not knowing when, what if he changes his mind? How do I bring this up?
<bot>: I want a somewhat more precise time of when we are having kids before we get married. It's a really important deal to me but my fiancé always brushes the subject away and I'm left feeling confused and worried.
