Some girlfriends (who do not know I'm pregnant) and I went to dinner tonight. Around 9 the place turned into a dancing scene and some people were smoking cigarettes in the area. I finished my meal over the course of about an hour and then left. Neither me or my husband are smokers so this is the only smoke I've come in contact with and it was only for about an hour in a big open restaurant/bar that was ventilated. Do you guys think my baby is okay? I'm 6 weeks.
