Not pregnancy related at all, just confused and a bit stressed.

So my fiance and I are getting married next week. Just a small, court wedding. We are saving the big wedding for when baby boy is here. The only person who will be at this one is my mom, probably. We are choosing to dress up a bit, nothing too over the top. I'm not sure if I want to take a bouquet though. Is that a thing at court weddings? Do you take bouquets there? I've only been to one wedding in my life, and I was 6 so I don't remember it at all. Do we just show up and say i do? Do we do rings there? Vows? I already know we have to go beforehand to sign and everything but i have no idea what goes on inside the room.what i do know is that it's going to be a group ceremony. I'm not sure how that works, either. I really hope we don't all say I Do at the same time.
