Work help

I am currently a care giver for a assisted living facility and I'm 3 months pregnant and it's just becoming harder to work there because many times I have to do heavy lifting,lots and lots of walking and sometimes I hurt my stomach hitting it against walkers or wheelchairs.I'm exposed to many germs and it gets really stressing and busy..I want to quit.what job should I get.any opinions.this baby will be my first
