My ex girlfriend just so happens its possible that it's mine do I have to Pay child support before the baby is born? I constantly offer to provide the things the baby needs but it's not good enough it's seems to me getting the money is more important than getting the things the baby needs I need advice..

No. You do not have to pay child support for a child who does not exist.But you may pay VOLUNTARY some prenatal expenses./including buying things for the baby/
