You comfort her by always be there for her because usually people who just miscarriage is in fragile condition. So just help her in anything she needs, cook for her and do some 'pantang' thingy because it is a must. Just continuously give her support.
Don't say anything. You can cook pantang food and ask her to rest well. That's what she needs the most right now.
Just being there and giving her a hug while lending a listening ear will help to comfort her
Sometimes we dont have to say anything. Just be with her. Cheer her up.
