Ok, I'm 5 wks today and we are taking a family vacay next wk to the beach. My father in law smokes so we decided to volunteer to drive my new suv so I wouldn't be subjected to the cig smoke for 6 hours in the car. We haven't told family we are preg yet (had 2 prev losses) he reluctantly agreed and said only if he could use his ecig on the way. My question is...should I be concerned about being exposed to the ecig for a 6 hour car ride (we will have him crack the window)??? I can't find anything online aside from concern about actually using an ecig while preg which obvi I won't be doing bc I don't smoke. TIA.
