Working while pregnant

Abbigail • Married and expecting a little boy on May 16th, 2016!! 💙😍 we love him so much already!
So today and me and my husband got into a little fight about me working. He wants me to stop at 36 weeks. I said I'd stop when my body told me I had enough. We got into it with him saying that he doesn't want me to go into labor at work. We finally agreed I wouldn't work past 38 weeks. I'm currently 23 weeks. How long are you ladies working?
