Wedding Etiquette-Pregnant

We jrecently found out that we are expecting and I was planning my wedding, now we NEED to move it up. I already booked the church, the hall, the flowers and the caterer. But I am NOT going to walk down the aisle HUGE. We don`t want to elope, any suggestions for a beautiful and tasteful wedding. I am 14 weeks and STARTING TO SHOW so thereisn`t much time. We were supposed to get married on what is now 2 days from my DUE DATE
Thank you
Susanna
