Please, please, please lil666, please give up the smoking thing, you are choking your baby. As long as you are smoking so is your baby, and his or her little body just can't handle it, it will destroy his growing little lungs. The baby is most likely to be ok at the moment, but when baby starts relying on your body more and more, he will end up being born with lung and breathing problems, possibly asthma. Smoking during pregnancy also stunts their growth apparently, so baby will be born underweight. I know a woman who smoked all through both of her pregnancies, and both her kids are very small for their age, and you can actually hear them breathing, there is a kind of wheezing sound with their normal breathing. The sooner you give up smoking the better off baby will be, don't worry about the nicotine in your blood stream, worry about the smoke in your lungs, your baby is in there trying to get a breath, and all he will be recieiving is a lung full of smoke.
Good luck lil'
