I had a high risk for miscarriage in my first trimester, so my doctor recommended that I work half-days until the second trimester. My employer required that I use my accrued sick time and vacation during that time period, so I have nothing left to use. We have no paid maternity leave or temporary disability, so I am left with nothing to cover th etime period I will have to be gone. Is there anything I can do for income during that time?

Sorry, no. If you do not carry your own private disability insurance and your employer does not provide a disablity benefit plan, then I'm afraid that's it.
