A lot of teens go through the baby rabies thing, but I would say give it time and allow it to pass. I mean, you're getting married, so why try for a kid right now? Don't you want to at least enjoy your marriage and enjoy your husband a little bit before dedicating yourself entirely to a shrieking infant?
The bottom line is that you've got about another thirty years to have a baby, so why rush it? You're in the prime of your life right now, and you want to throw it away to be a mother? Having babies at any age is difficult, unless you pawn them off on grandma or a nanny so you can live normally.
I agree with natalia - if you have to ask us whether or not you're ready to be a parent, then you should already have your answer. Finish college, enjoy your marriage, and try to have a little bit of fun too. If you have a child, you will be unable to do any of those things.
