What type of prenatal care and services are needed in pregnancy?

My husband and I just found out that we are pregnant with our first child. We don't have any health coverage whatsoever. Although, we do make a living w/o gov't/outside assistance, we still survive "check to check." Thus, leaving us with the daunting task to find/afford self-paid/pre-paid prenatal care. While the financial aspect will sort out either way, in the meantime, what type of prenatal care should I seek immediately? Our pregnancy was confirmed with an HPT. What's next? Sonograms, bloodwork...or, will simply finding a doc set me straight? I should be atleast 2-3 months pregnant by now. Thanks so much.
