Overwhelmed..

I just found out I am expecting and my edd is August 31. We are currently in the middle of planning our wedding, our date that we picked is September 10. Obviously we either have to move the wedding back or push it forward. My dress will be here between February and April. I'm not sure what to do right now. If we get married sooner then I will be downsizing the wedding by ALOT I'm just not sure what to do right now.
