Working and Pregnant

Well, my husband has been hinting for me to quit my job for a while now and last night just came out and said it. I am thankful we are financially able to have me at home, but work is my escape. I work at an assisted living as an overnight LPN, I love it. Lately though there has been an illness running around the building and I picked it up. I'm off to the doc today to see what is going on with it. Any other working pregnant momma's not wanting to quit just yet? I'm 22w 2d by the way! My husband is primarily concerned with me lifting so much and sleeping so little it is some how affecting the baby...
