Exposed to paint for 3 hrs at 3 months pregnant.....

So I had to clean an apartment today that had just been painted the day before and was still being painted when I arrived (I was not informed about this). All the windows were closed so the smell was really penetrated in there. I started opening all the Windows, but the smell was still in there. I lasted 3hrs in there although I was feeling dizzy, weak and nauseous as of the first hour. :-/ how can this affect me and the baby?? :-/
