Born early at 24 weeks. Please pray.

My daughter, due at the end of June, was born this past Thursday at 24 weeks when I started bleeding and wouldn't stop. (I think my marginal previa let go).
She's fighting to live in the NICU and I'm fighting to not lose it. I'll be devastated if the child we fought so hard for doesn't make it.
Help me hope. I wasn't ready to not be pregnant anymore any more than she was ready to leave my body.
