Baby or Wedding

So I recently got engaged and I'm over the moon happy about it and I am ready to start planning my big day now. My fiancé however, wants a baby first. He will be 31 in a few months and I understand he still wants to be young enough to enjoy little ones but I have always envisioned being married first, then babies. What are your opinions? Should I let it go and one day get married and have my little one there along side me or should I try for a wedding first.

On a side note, we were pregnant earlier this year and had a missed miscarriage and after healing have been trying to get pregnant but we are having some difficulties
