What does he say about getting a second job? He probably doesn't know that you feel that pressure and he probably feels it too. Sometimes men retreat into things like video games to escape stress. He probably feels it as much as you but does something different about it. He may feel you will make it through or he may want to get a different job instead of a second job. Let him know how you feel and try not to take all the pressure on yourself to work two jobs. That may not work for you and how tiring it is to be pregnant.
I agree get a forbearance or deferment you most certainly can! That's one less headache. Next put the video games on eBay! ! !
One thing you could look in to short term is asking for your loans to be deferred, or put in forbearance. You may possibly qualify for a reduction in the amount. I used to work in financial aid & know that many people forget that there may be options to help temporarily. I know that doesn't address the issue with your husband, but I thought it might help. You may may want to talk to him about your concerns. Good luck to you and your family.
A man does what you allow him to do...let him know that its not acceptable-you can do bad by yourself...if he's not contributing to the well being of you or yalls unborn child, whats his purpose?
