Job interview at 7 months?!?! Help!

April • Pediatric/ Family nurse practitioner and mother of 3: Celeste (9), Aniston (5) & Abel (Angel baby 16 weeks).
I have an interview coming up for a one day a week teaching job. I really want it because it'll help with work/ family balance but I'm worried they're going to take one look at my belly and say, "no way!" Any suggestions?
