When you give birth, the hospital will ask who the father is. At that point you would tell them the dad's name. When you're ready, you can go to Child Support Services to request child support.
There is no such thing as 'giving up rights' to a child. If you were to marry, your spouse could file for a Step-parent Adoption and if the dad agrees, he would then be giving up his rights.
