Warehouse work while pregnant?

I'm currently 15.1 wks pregnant & job searching.  There's a local warehouse in my area that is having a job fair next Friday to hire 100s of workers.  The pay & benefits are good but I'd constantly be lifting things 50lbs+ everyday & the shifts are 10-12hrs long standing.  I'm starting to get desperate with the job search now because I only have 5 mths until my baby's gets here & I have no financial support from anyone.  Confused about whether are not I should apply for the job.
