Dropped bridesmaid

For everyone asking why she would need to drop out, are you her doctor? This is a medical condition. She's due 2 weeks after. You say all she has to do is show up in a dress and stand up. Easier said than done, especially since her first pregnancy was rough. If I were pregnant, I would probably drop, too, because I am at risk for being high risk, and at 38 some weeks I shouldn't be in front of the wedding, especially standing.

OP, I agree with others, she can just be a guest instead of having role, if she can make it. If she still had something to do, then it would be pretty much be the same work as being a bridesmaid for her. She can be close to you when you're getting ready, do a reading, and she could get involved if she wants with your bridal shower.
