Actually, I am not sure how the rules are in your state, but I think your doc would have to continue seeing you. Plus, considering they are seeing you already, they have to realize you need the doctor, obviously you can't just stop being pregnant.

I know you may not want to do this, but you can go and get WIC while you are pregnant, this won't provide you with a ton of food but it will give you a good bit (it was what I pretty much lived off of when I was pregnant). Also you can apply for food stamps and I would bet that in your situation you would even qualify for emergency food stamps (you get those almost immediately while they are reviewing your claim). There are also lots and lots of programs to help with paying utilities. It sucks but for now you should get rid of everything extra, internet, cable, keep a phone, but if you have multiple cell phones cut them off. The most important thing you can do is take care of yourself right now. Its really hard to ask for assistance like this, but it is what the programs are there for. If you don't mind me asking, how did you lose your insurance while you were pregnant? There may be something you can do to get that back.

And your mental state is just as important as your baby. Remember you are carrying it, so you have to be healthy too!
