I don't understand... Why doesn't he think that your finacially situation is dire enough to go get a job? Do you have another income coming in? Are you spending your savings?
And what do you mean by waiting for his night job? Is it already lined up? Is he interviewing? If he already has a job lined up that will start very soon, I can see why he doesn't want to interview and start training for another position, only to leave it in a couple of weeks.
If the situation is as bad as it seems, and your talking to him repeatedly (which sounds like the case) hasn't gotten through to him, I would suggest enlisting the help of his family members. In normal circumstances, I would NOT suggest interference from any family members, but two things come into play here: (1) you need to think about what's best for the baby, and stress over finances and a non-motivated husband should NOT be on your radar because any dr. will tell you how this adversely affects the pregnancy and (2) if it's feasible, and onlyif it's feasible, ask his family to help you persuade him. Asian men have a tendency to be persuaded by their families, and surely, if you have that sort of relationship with his folks, they would see this as helping their unborn grandchild.

Good luck!
