What NOT to say to someone who had a m/c

Darcy • 31 y/o happily married. Can't have a rainbow w/o a lil rain. 💦🌈 😇mom to 2 Angels &1 rainbow due 3/24/16. IUI/ Clomid
I've gotten them all:
"It will happen when is meant to happen"
"Don't worry you will have a baby soon"
"You just need to have more sex"
Those almost make it worse. 
....
What else have you all heard? And possibly suggestions of what to say instead? I appreciated just a sincere "I'm so sorry. Is there anything I can do for you?"
