I'm looking for Insurance that will cover my pregnancy?

I thought I would be able to get on Medicaid. But one look at my husbands check stubs and they said there was no way. I tried to explain to them that the overtime on that check rarely happens but they would not allow me to apply. So my question is, are there any insurance companies that will take me and not see my pregnancy as a "preexisting condition"? I have been looking and though i found one I haev not found very many reviews on the insurance agency so it makes me weary. If you have any kind of info for me I would GREATLY appreciate it. Thanks in advance:)
