What do you say...

Just tell her that you're there for her if she needs you. Bring over a supper so she doesn't have to worry about food. Let her talk and just listen. Offer to help out in any way that you can.

I know that when I had a miscarriage that was very painful emotionally I had a lot of people who would ask how I was doing and I always answered, fine. I learned through that when I ask others how they're doing and they say fine to say "Now how are you really doing?" That opens it up that you're willing and have the time to talk to her if she wants to talk about it.
