Medicaid

I was 18 when I got pregnant (will still be 18 when he's born). We were engaged before getting pregnant. I had Medicaid before getting pregnant (I was a college student). Should I still have Medicaid after the baby comes if we aren't married? If yes, will getting married make me ineligible for Medicaid (his income is still considered low)? I'm currently taking a semester off, but will return in the summer or fall. We really cannot afford for any more money to be taken out of his check.
