What do I say and do?

SD
My friend tried for 3 years to fall pregnant and went through two cycles of <a href="https://glowing.com/glow-fertility-program">fertility treatment</a>. She finally fell pregnant naturally and been having a rough pregnancy. Today was her 11 week appt with Dr. She was told that baby stopped growing at 8weeks. She is booked for a d&c tomorrow. My heart is so broken for her. Please tell me what do I say to her. All I could do was hold her. I just had my baby 5 months ago and I feel like I can't even talk about her now because I don't want my friend to hurt more. Please tell me if there's anything I can do to help her. Or anything I shouldn't do or say. I'm devastated for her.
