Girl, go to a pregnancy resource center. They can help you financially. You are not alone in this. Laws very from state to state, but most states have financial help available to women like yourself. Here is a link to a website that can help you find financial assistance. They might not be equipped to help you when you go in, but they should be able to refer you to where you can get help in your community.

At the website all you have to do is type in your zip code and a list of centers will appear. Just call the center and tell them that you need financial assistance. They will be happy to help you.
