maternity wedding dress what a joke

We are having a courthouse ceremony on June 22nd and I'm in tears because I can't find a fucking dress that looks decent and is comfortable. I'm so beyond frustrated. I've tried on so many. I'm super short and plus size already so add in twins and I'm fucking huge. I can't stand next to my bf in his custom made shit while I look like shit. I don't know what to do. family have taken off of work for this so I can't in good conscious just cancel it anymore. help.
