Need advice for first time pregnancy!

So me and my fiancé have been trying to get pregnant for about a year now and for some reason the nervousness is setting in for me. Our wedding is set for October of next year only because both of my brothers are military and they could only be here if it was two years in advance. I know I want to spend the rest of my life with my future husband, that's not the issue I guess I'm just starting to worry for the simple fact of having a baby before the wedding. Should we wait another year or just go for it?
