Wedding dress and pregnant

Stephanie • 37 yo, EDD 11/14
Hello Moms! I'm currently 14w and a ftm and I need advice on buying a wedding dress. I plan on looking for a short dress, or a formal dress that comes in white/ivory/silver but isn't a wedding dress. What's your tips on buying a dress for a growing body? Based on our timeline I'll be anywhere between 21-30 weeks (have not picked a date).
