My sister just told me she and her husband are trying to get pregnant. I'm happy for them, but my wedding is in Vegas in November, and she basically said she wouldn't be able to travel if she is beyond 7 months pregnant. She is my MOH and now I'm stuck with the "what if" parts of the situation....What if she gets pregnant from now or in the next 4 months? I can't just have a "backup" MOH. Am I being selfish or is it reasonable to consider removing her from the bridal party? Also, my wedding is on the rooftop of an upscale hotel, and in the event her and her husband can't go I am spending an extra $1,000 for 2 people who won't be there (I'm paying for all inclusive on a per person basis). Thanks!!
