TTC and wedding

My fiancé and I have been together for over 5 years and we own a house together and all finances are together (other than marriage certificate we’ve basically been married for years). We got engaged recently after trying to conceive for 6 months with no luck. Our family and friends know we’re engaged but don’t know we’re ttc. Everyone is talking about the wedding and are shocked I haven’t planned anything yet but truthfully I’m not sure I would want to be pregnant on my wedding day but I’m not sure I could handle not trying for a baby right now either. Has anyone been pregnant at their wedding, if so how was it? Any thoughts on putting a pause on ttc or pushing back a wedding without needing to tell everyone we’re ttc? Even if nobody has thoughts about it I’m glad I have a safe space to rant.
