Some one help.

A week today I'm getting married, problem is we still don't have an ordain minister, I'm 8weeks preg. Tomorrow and idk if it's the stress of the wedding or the baby talking but I feel like I'm falling apart, I'm so stressed I'm crying I think it's cold feet, idk, but what can I do? We've been planning this wedding for 3 years and the person that was supposed to marry us bailed out last week.
