Smoking while pregnant.

Ughh frustrated! I am 6 weeks pregnant, I have been smoking since I was 14 I am 21 now. I am desperately trying to quit but its been very difficult! I have cut back from a pack to about 7 a day I have tried the cold turkey but wound up driving to the store at midnight after going all day. Any advice on quitting? I dont want to harm my peanut!

Are non nicotine cigarettes a bit better till I can fully stop? What about no smoking but maybe the pouches? The patches are a no as they give off continuous nicotine. Any ideas??????
