Help! Painting at work

So they are expanding a meeting room at work. It has been incredibly dusty and absolutely stinks of chemicals and paint. Today I left work early because I couldn't handle the smell. I was so nauseated all day and I can't help but wonder if this is harmful to my baby. 😞I'm only 5w3d and haven't told anyone at work. I think I need to tell my boss. Thoughts? Overreacting?
