Hi,
I am really sorry to read what all you have been going through. Hope, hard times get over for you. I think the foremost thing that you can do, which comes without money is, stop being stressed as it is anyway not solving anything, rather if you continue to be one, it can add to problems. You know, how important it is for a pregnant woman to be happy. Remember that your stress is travelling to your baby. So, be happy, because this is the only thing that can make the situation little better.
I suggest, take little support from your family. Ask your husband if there is any way that his family can support you guys for sometime, or any of the friends who can help you financially and you can pay them back after sometime. Figure out whether you can take your salary in advance,as there is provision in some offices where you can withdraw your alarm in advance as well.
Hard times come to everybody's life, and at such hour firstly you have to got to believe in yourself and secondly in front of whom you can open up your heart is your family and friends. So, do not feel any inhibition and talk to your family or friends. And then you can have a follow up and can discuss the financial aspect with your doctor as well, and how he can help your case.
Keep the faith, all will be fine.
