Bridesmaid @ 8 1/2 months pregnant, Update

Hi guys! I am supposed to be in a wedding, at the time of the wedding I will be 8 1/2 months pregnant. The wedding is not until October. I do NOT want to be in the wedding- any suggestions? 
I talked to the bride again today and I am out of the wedding. I explained everything and she took it well, very understanding. Thank you all for the help- I feel relieved!
