Job searching?

I'm at a complete loss right now and don't know what to do. So I got fired from my job back in October. It's required that I apply for jobs weekly and go through any interviews and what not that's offered. I'm 35 weeks and 1 day. I have an interview tomorrow and I don't know if I should tell them or not. I'm still small enough to hide my bump. But me and my fiance also agreed that it wasn't ideal for me to work right now. Any advice or opinions would be helpful!
