So scared and broken from this

I need to just let a lot out. I'm nearing 18 weeks and have yet to see a doctor. Between insurance and one incident of my daughter being very sick I've had every appointment cancelled. I am too poor to have insurance willing to pay for a baby so I'm struggling more, I don't get it. I call and call the insurance and they claim they fix things and then the OB calls and cancels, AGAIN. I am losing my mind in fear. I've had two miscarriages and I'm so so sick this time, I just feel like the state is trying to kill my baby because I don't have a lot of money. How can a place treat people like this?! I can't see a doctor within hundreds of miles and the one that's given me hope right down the street won't see me because of money. I'm just so scared and tired right now.
