I'm currently 21 weeks pregnant. And have a job interview at a nursing home for nursing assistant. I signed up for second shift because the load won't be as bad as first shift. But didn't do third shift because I'm scared I'll be falling asleep all the time and get fired.

Question is should i tell them at the interview I'm pregnant cause this can restrict me from doing too much. But I'm still capable of working. Should I wait till I already have the job? I'm not really showing that obviously. I'm a chunky girl so I Just look fat honestly. This job is really my last hope. My other option would be moving back home with my parent 2+ hours away from the dad.
