I am a regular smoker and take 1-3 cigs per day. How long before I stop in order to conceive? Will I be able to conceive a healthy child if I stop a month before conception?

I quit after knowing that I am pregnant for 7 weeks. It was immediate though, and no cravings for cigs. I used to smoke at least 20 sticks a day. Baby has been growing well so far. But of course it's better to quit and have a healthy lifestyle At least 3 months before trying to conceive. Eat well, live well, make sure you have necessary supplements to prepare your body.
