Should I tell my potential employer I'm pregnant?

So I am almost 33 weeks pregnant and was just advised this week that I am apart of a layoff. My due date is November 19th layoff date January 2nd. I have an interview within the company soon. Completely different department. I work at home and the position is work at home too. All interviews would be done via phone. Should I tell them I'm pregnant or wait until I get an offer? Just not sure what to do.
