Mom's wedding 11 days after my due date.

Joshalynn • Mom of a beautiful boy Samson, 5 years old. Another beautiful one due Sept. 1st 2015!
I'm due sept. 1st and my mom just booked her wedding today, for sept. 12th. So either I'm gonna be huge and overdue in my bridesmaid dress of have a less than 2week old baby at her outdoor wedding. Is it selfish of me to think that this is a bit inconsiderate?
