How do i help

My friend is PREGNANT. She just found out on monday and im worried about her. She also was just at a mental hospital for like over a month so her family definitely cant afford her to have a kid. Her mom knows and me and my sister know but i dont think she told her friends. She always said that if she got pregnant she would keep the baby but shes poor so she cant really afford that. And she isnt in a relationship with the guy (who ever it is cause i dont even know). Im just worried about her shes only 16 and i want to help her but i cant because i have no money. If anyone knows a cheap way to help out a pregnant friend that waould be great.
