CNAS work while pregnant?

I work in a nursing home, meaning I lift residents and am on my feet almost constantly, I'm not pregnant yet that I know of, but since my body is already used to the lifting do yall think I'll be alright? I don't really have much choice but to continue doing what I'm doing...but I may be able to talk to my DON about changing position. What do yall think?
