Today I went to work, had a couple of appointments, did the girls' nails ????, sat for almost 3 hours — the smell of the base coat was awful, I literally felt nauseous. When I wasn't pregnant I didn't really notice the smell, but now I can smell it very strongly; I could barely sit through it. Now I'm wondering whether I should keep working or not risk it??? I don't know what to do ?? Please advise — do these smells affect the fetus?!
