stressful pregnancy....

So when I had my docs appointment something went wrong with the insurance an nothing was taking out. something to do with my deductibles. Well they said to apply for a medical card so I did. Just so I could stay attending there bc I wouldn't have money to pay monthly.. An I'm just getting to that point we're if I don't get excepted for the medical card. I no longer want to attends doctor visits bc I don't have money to pay monthly... What should I do..
