Suddenly and wrongfully terminated - need help

Hi, my name is Melissa and I was let go very suddenly (for the first time in my life) from my job on November 30th. My work found out I was pregnant and wrongfully and suddenly terminated me without cause. I am trying to find as much contract work as possible right now and applied for unemployment, but still haven't seen a dime. I am seeking legal help but do not have money for a retainer, so I am looking for a contingency only lawyer who will take my case. I am in desperate need of help just to make rent in the next few weeks and make my car payment and pay utilities. I have two sons and a baby girl on the way. I have always been the person to donate when I can, so my hope is that good karma exists, as I never imagined myself being in this position. I appreciate any help anyone can offer.
