I have been a smoker of the endo for a long time, now, and I have 3 kids, all almost grown. I remember when I was pregnant with my 1st child, I took a toke from a joint, and my baby kicked up a storm, and got really active inside me. I got really scared, and never indulged again while he was in utero. With my 2nd &3rd preggers, I lost my love for it, due to the fact that to me it smelled like fecal matter on fire, and made me want to vomit every time I smelled it. I also had friends that never stopped indulging in the wacky tobaccy thru their pregnancies. One in particular has 5 children that are seriously problematic. Uncontrollable in school, at home, in public, etc. and their grades are lousy. So I guess the choice is yours, but I would recommend NOT smoking while you are pregnant, I think it will be better for both you and your baby. Besides this time will pass quckly.
