Hi girls! When I didn't know I was pregnant I smoked hookah every day. I don't smoke cigarettes, and I never used to. But I love hookah. When I found out I was pregnant I was three weeks along; the test showed pregnancy but it wasn't visible on the ultrasound because they said it hadn't implanted in the uterus yet. I stopped smoking hookah immediately. I'm very worried whether this will affect the baby ?
