Self Employed, Can’t Afford Coverage, What Do I Do?

So my wife and I are self employed make less thank 30,00 a year and income fluctuates in a year to year basis and o did I mentions she is pregnant. We had Obama cars for 2016 with help with tax credits which as a great help but for 2017 I found out our rates have nearly tripled up to the pint were we will be paying up 300 for premium costs. Now let’s not forget that we make less than 3000 a year and that fluctuates, I can’t afford to pay 300 a month for insurance. O and they said now my wife qualifies for badger care So that’s all fine and stuff but for a single person me who has to get coverage or apt a penalty ridiculous amount of 300 dollars a month sorry but I can’t afford that so my wife and I decided that for the 2017 year I go with out the insurance and we’ll pay the 700 tax penalty and maybe next year revisit it and pray to god that we qualify for some tax credits. Ugh I really hate ACA I understand it’s needed but the hike that it increased to and how it works against husbands with pregnant wife’s is so unfair.
