ok or too risky?😩

I'm 5 weeks 3 days, my job is really long hours from 6am till 10pm.. I only have like 1 hour and half break. I'm constantly standing and walking to patients houses as I'm a health care assistant in people's homes, so I'm not getting proper meals just like a sandwich or something, no rest and 5 hours sleep, do you think this is a big risk to mine and my baby's health? I would rather quit my job and find another rather than risk my pregnancy as I have weight problems anyway (under weight) what would you do?😔
