would you say something to your boss?

I'm currently 35w +3d. My boss and co-workers are fully aware of this fact as they threw me a baby shower. My problem is they still have me working overnights when my OB has expressed she does not want me to anymore. I also walked in tonight and was told I had to set up the meeting room (I work at a hotel). Usually this is no problem but at my 34w appointment I was told to limit any heavy lifting. I have to take down 4 tables and bring them down the hall to the storage room then bring back 20chairs.

I'm just wondering should I bring this up to my boss. Her usual response is that I'm pregnant not handicapped but I feel like this close to my due date I should really not be lifting heavy things. I also saw there's another set up next Monday that requires more moving of tables and chairs than tonight will
