smoking while pregnant.

Kaitlin
Okay, please be kind. 
I wasn't planning my pregnancy one bit. I am currently 4 weeks 5 days pregnant with my first baby. I already talked to my doctor about quoting cold turkey. He told me that's a bad option simply because it can shock your body. So I guess I'm looking for ideas on how to stretch out the process of quitting. 
Please be nice, I'm an emotional wreck and already feel like a bad mom. I don't need your two cents about how it's bad. I already know, that's why I'm trying to quit.
