17 year old mother seeking advice.?

The legal definition of an adult involves becoming 18, not 17, so I do not see how 17 will change anything. In most states you can petition for emancipation once you are 16. I am quite surprised that your Human Services Department (or whatever it is called in your state) has not already contacted you due to your age. You might want to consider calling them, as they don't just take away children, but also offer support and services for young mothers.
