No Health Insurance!

So...today I am 15 weeks pregnant. I've been struggling trying to find health insurance for myself so I can see a doctor. Obamacare is way too expensive (they want $300+ a month just for me! so much for "affordable healthcare") I've applied for medicaid as a last resort, but have still heard nothing. I have a 2 1/2 year old son who was born Prematurely. I had PPROM (Preterm premature rupture of the membrane) at 29 weeks with him. I am considered high risk, but don't know what to do! I should have been seen by a doctor 6 weeks ago! Any advice? There isn't a public health department where I live.
