smoking before you found out?

okay so, i did blue dye tests, they turned up a faint positive. i did pink dye tests, and they’re negative. well, here i am, 2 days late (and thats 2 days later than my longest cycle i’ve ever had) i got really upset when my pink test turned out negative and smoked cigarettes here and there, and now i’m worried i am truly pregnant and i might have done some kind of damage.

fyi: i’ve been taking prenatals alll month, no drinking, no extreme exercise or drugs, one caffeinated beverage a day, you get the point. anyways, i know the first few weeks after you find out usually don’t harm the baby, but, i just want some honest answer. thanks guys!
