Hello, I m 19 years old, and my boyfriend and I are going through a pregnancy scare. As of right now, I am not sure if I am pregnant or not, it s too early to take a test yet without going to the doctor. My question to you is actually about me smoking hookah tonight. It s the first time I have smoked hookah in months, and I was wondering if it could have any effects on the fetus IF I am pregnant and just don t know it yet. If I find out I m pregnant, I will for sure quit smoking hookah, because I just do it socially, but will this one hookah session affect this baby?
