Can I collect disabillity for unpaid maternity leave?

I bartend for a living and my income is about half what it used to be because i switched from nights to days to protect the baby. I had to pay out of pocket for the first 3 months while waiting for my ins to kick in. i also moved once already and have to move again. I'm 33 weeks pregnant and broke. I have to take 6 weeks off with the baby(uming i can work until he arrives) because i don't have family here to help me and I can't get day care until he is 6 weeks old. I also really want to feed and bond with my son. I still make too much money to even qualify for WIC. I can't work the extra hours i was in the beginning, its too much now. Anyone have any advice?
