your friend needs to see a Dr and make sure her baby is safe and sound. She needs to grow up and take responsibility and needs to stop blaming herself or anyone. The issue is identified now solutions are required not blame or shaming anyone, we are talking about a baby's life here.
This goes to the "boyfriend" he needs to be a man and take responsibility and get married to your friend asap.
Find out if there is any association that can help her go through this.
We all make mistakes but if she's a beleiver tell God is forgiving if you forgive yourself and change for the better.

Bless you for helping your friend and let us know if we can do something.
