I'm in Ohio and I need help with insurance and healthcare/treatment?

I am 27 yrs old, jobless (disabled) homeless, no car, no license, and now no insurance. Oh yeah, I'm 21 weeks pregnant too. I have been on opiates for over 10 years and now have been trying to get off them for over 1 year, lng before I found out I was pregnant. The problem with being addicted to opiates and being disabled is despite the fact that I have come off of them, and I mean ALL of them, vicodin, percocet, oxy, roxy, etc. *I DO NOT use street drugs, have refused methadone and suboxin and I would rather go to rehab before I would stoop to using heroin or anything; the problem is that the dr's will only put me back on these drugs or even worse, they won't put me back on them when I need them. I need surgery on my spine, am trying to get medical istance and now my prescriptions are due but they cost over $500 altogether. I am scared of withdrawing and being pregnant, the dr's have been slowly weening me but it just isn't good enough for me (I knew I would wind up in a shituation like this, have no help or support, my family doesn't know or understand my struggle with these meds and being dependent on them). I need to find healthcare coverage like yesterday and I am also willing to do whatever it takes to further avoid any more problemds from living like this. Any advice helps. It's butler county by the way.
