Need urgent help!

So I am pregnant! Which wasn't expected. I'm excited but I'm really scared too, because I am from the U.K, I came here and got married on a specific visa 7 months ago and I'm waiting for my greencard. I don't know what to do? I'm not insured neither is my husband. We're scraping past bills as it is because I can't work until I get my greencard, so all income is purely him. I can't be a public charge so we can't get government help and we can't afford insurance. I really don't know what to do or who to speak to
