Disclosing pregnancy during interview...any advice or experience?

Jillian

I'm 22 weeks and have a job interview in 2 days. I can still conceal the bump somewhat, so I don't think it will be obvious that I'm pregnant. Just trying to decide if I should let them know now that I'm expecting or wait until I have an offer. If I was only in the 1st trimester, I would wait until I had an offer to disclose. But since I'm close to the 3rd trimester now, I'm leaning more towards being honest and letting them know now. I've had a phone interview already and got good vibes from the woman who will be interviewing me. Anyone dealt with a similar experience or have any advice?
