29 weeks preggo an have a JOB INTERVIEW!!

Well obviously the job interview is today and I am really excited because my bf could use the extra income. We discussed this and he thinks that I should've told them I am pregnant. Where I think it's better that I not mention it until after I am hired because it's pretty OBVIOUS I'm preggo. The job interview is today idk what to do should I still go or not even waste my time ? Help!!
