Miscarriage help!

My best friend just had a miscarriage. She was 13 weeks along. Any suggestion on a kind gesture or something I can do for her? I want to give her space to grieve but it just kills me that she's hurting, I want to be there for her. I'm 8 1/2 months pregnant and don't want to make anything harder on her either or overstep. Any suggestions please. I'm lost on what to do.
