Insurance help!!!!!!!!!

So me and my fiance recently discovered I'm pregnant... I am recently covered on medicaid which of course would carry over now due to my pregnancy (I'm 19) and my fiance brings home about 1,700 a month with me being in college it's only 600 on my part. Every one wants us to get married before the baby comes since we were engaged anyways... My big question is would we qualify for medicaid or would I be kicked off of my medicaid if we get married??? Please help... I'm so stressed....
