No insurance

Hi I just need some advice I’m currently 5 months pregnant. I tried to apply for health insurance and I don’t qualify bc I make “too much” I’m a single mom . I have a 1 year old and the one in currently having I pay all the bills and I feel like they didn’t really check to see any of my bills they only asked how much I made and how many people on the house hold . I currently owe 2k in hospital bills now and every time I go to my pregnancy appointments they charge me but I can’t afford to pay everything. I don’t know what to do are they able to stop seeing me for my appointments if I don’t pay ? Or are they able to wait ?
