Opinions please!

I have a situation that I'd like to get some opinions on.  My cousin (and also one of my best friends) is getting married May 2016. I am the matron of honor in her wedding. Back in July my husband and I decided we were ready to start TTC baby #1. Now I'm feeling conflicted because I'm almost 100% sure the bride would not be OK with me being pregnant at her wedding, mainly because I have a lot of duties to fulfill (planning bachelorette party, etc.) and I feel like she would be really upset if I got pregnant before her wedding. I'm 26 and hubby is 28 so we're not getting any younger. 😜 anyone have any experiences similar to this or any advice?
