how to support family member who had a miscarriage?

I just found out that a family member suffered a miscarriage earlier this week. She has her mom with her, she married a 2nd cousin this past summer, so she is in good hands. I'm in Michigan and she is in Metro Toronto, I feel helpless.
I got the news from my 2nd cousins dad. The young lady, she's around 25, started dating my second cousin when they were around 14 so she is a long term member of my family in my mind. I am the oldest female, by blood, on this side of the family so the men have some questions.
She has to go in on Friday for a D and C, that I was able to explain to them. They wonder how long before she would be able to start trying to start a family again, and how long before her and her husband can even be intimate again. These are questions that the men have and they feel comfortable asking me being their blood.
Any help would be much appreciated and all will be past on to my men, as I call them.
