Painting while pregnant

Shelbie
In the summer I planned on taking on a small painting job at my school. It would only be a couple hours a day for 4 days a week. The paint isn't oiled based and I would wear a mask, keep rooms ventilated, and take breaks. Even to go as far as dropping some vanilla in the paint for the smell. Has anyone done this or heard pros and cons. I plan to ask my doctor next week at my appointment.
