Sandra: My ex husband's workplace(s) refused to allow me on their health insurance. The divorce was final in one year. I am on Obamacare and pay over $300/month. If your son's wife cannot afford any kind of Obamacare, I would think she would be able to apply for Medicaid, especially since she is pregnant and if she is turned down, I am sure there are people at her Doctor's Office who can help her find something, depending upon what is available where she lives and her income.
