I was able to find work 'to pay the bills' early in my pregnancy by hand delivering my resume and a cover letter to a number of places. The work wasn't in my field, but was close ish to home and although the work was at times boring, the people were lovely and i returned there between the two kids, and then got some project work that could be done from home after #2.
Cold calling was way outside my comfort zone, but it worked for me and gave us the money we needed.
Good luck.
