working

Okay so I am 33 weeks pregnant, I am a nurse aide, well I work at a place that I am the only caregiver in the house for 3-5 residents, I cook, clean and give them meds. It hurts me to try and change one of the residents by myself because she doesn't stand very well and she buckles her legs. I really need the money so I am trying to work until I give birth, but I am so afraid of hurting myself or the baby, if you guys were in my aituation what would you do?
