Getting married and pregnant..

My fiance and I have been engaged now for about a year! We have the majority of the wedding planned out as well as rsvps, venues, etc. Thankfully the dress I bought is an empire style gown...but in the breast part of the gown it's super fitting...well since we figured out I was pregnant (I'm 10w.) My breast size has just about doubled!! I want to look great for,the wedding but,so far it's not looking so well. I've already gained 10lbs. I'm 5'0 and I weigh 150 :( is anyone else engaged and just found out they were pregnant?
