DH and I had been invited to a dear friend's 40th birthday party this weekend. He lives 3 hours from us, and we would be staying at his house. The problem is, the "party" will take place at a martini bar and a bowling alley. Now I obviously won't be drinking or bowling, but those 2 places sound like they will be smoke-filled. And I won't be able to just leave and go home if I find they are too smokey. I'm still in early pregnancy (8 weeks 3 days). Do I have a reason to be concerned, or am I just being overly-cautious? thanks
