<human>: My cousin who we will call Dana can be a rather overdramatic individual, but so far she's been chill about everything with the wedding. We went to the same college and were roommates for one year in an apartment nearby campus. We're still very close. She asked me to be her Maid of Honor, and I accepted, I was thrilled.

My husband and I found out we're having a baby right after the wedding, two weeks later in fact. Given that I will be nine months pregnant at the time, and that there's even a chance I'll be doing one of a hundred things like in the hospital, going into labor, on bedrest, etc, I will obviously have to drop out of the wedding party.

What is the politest, nicest way I can convey this to her? I want her to know I'm still going to be supportive and try to help as muc has possible, but I will have to focus on the bun in the oven instead of her. 

Thanks, /r/relationships!
