One of my Internet friends, who I've know for a few years now and care for deeply, just announced she's pregnant. She's not that far along, having just missed her period three weeks ago.

I've already sent her the proper "I'm so happy for you!" and "Praying for you!" (she's a much more "devout" Christian than I am) messages.

That said.

She's had three miscarriages already, all within the first trimester.

What is the best way to support her with this pregnancy, knowing another miscarriage is possible? Are there certain things I should say or avoid saying? I just want to be loving and helpful, without being inadvertently hurtful.
